At 60 mnp the force of your car impacting a surface is how many times as great as 30 mph?
4 times the impact. The formula is 1/2 mass times velocity squared.
What is the lbs per sq ft force a 9 lb object traveling at 34 mph?
Without knowing the surface area of the moving object, there is not enough information to answer this question. Rephrase and resubmit.
How do I find the speed of a vehicle when all I know is the length of the skid marks 24.2 metres and the pavement was wet at this time with a very slight slope down?
To find the speed you would need to find the time taken to create the skid marks and then use the equations of motion. As the vehicle is skidding, the wheels are not turning so the braking force is the friction between the tyre and the road surface; this has to overcome the forward speed of the vehicle and the forward force of the weight of the vehicle along the road (as there is a downward slope). The forward force of the vehicle can be calculated by knowledge of the mass of the vehicle and the angle of the slope. The frictional force generated can be calculated from the coefficient of friction between the tyres and the road surface, and the mass of the vehicle. The road being wet will reduce the coefficient of friction of the road surface/tyre boundary compared to when the road surface is dry. It is easier, by experiment, to do a few test runs using a vehicle of similar mass under similar conditions to get how the vehicle is likely to have slowed down when it skidded, and extrapolate/interpolate to the given distance of 24.2 m.
How did you find the Force on inclined submerged plane surface?
The best way is to find the centre of surface of planar area. Then the force due to hydrostatic pressure will be:F = d h0 g S,where:F is force,d is density of fluid,h0 is depth at the centre of surface,S is surface of the area.It works because when we consider the centre of surface, there will exactly as much surface with lesser pressure effecting on it as there is surface below the centre point where the pressure is higher.The net force vector will be perpendicular to the area at the centre of surface point.
If you divide the force exerted on a surface by the total area of the surface you will know?

Does your vehicle traveling at 20 mph the force of the car impacting a surface is two times as great as 10 mph?
No, the force of impact is not directly proportional to velocity. The force of impact is determined by factors such as the mass of the vehicle and the effectiveness of its brakes in stopping it.
At 60mph the force of your car impacting a surface is times as great as 30mph?
4 times.
At 60mph the force of your car impacting a surface is about four times as great as 30mph?
When the speed of a car doubles, the force of impact quadruples due to the relationship between force and kinetic energy (which increases with the square of velocity). This means that a car traveling at 60mph will experience roughly four times the force of impact compared to when it is traveling at 30mph.
Does Crash severity increases with the speed of the vehicle at impact?
Yes, all things being equal, crash severity does increase proportional to the speed of each vehicle at impact, and is a vector sum. So, there is a big difference between crash severity at impact from being "rear-ended" (when one vehicle is traveling the same direction as another, and impacts the front of their vehicle with the rear of another) and a "head-on" impact (two cars traveling into one another, impacting both front bumpers). In the rear-end impact, you take the momentum (mass times velocity) of the rear, impacting vehicle "A" and subtract the momentum of the front-most impacted vehicle "B", and that gives you the resultant impact force (the difference in momentum being transferred). weak impact scenario example: vehicle A is traveling 60 mph, and vehicle B is the same mass and is traveling 50 mph. The difference in momentum would be the mass times 10 mph...not much. severe impact scenario: vehicle A is traveling 70 mph, and vehicle B is at rest (0 mph)...large impact. In the head-on impact, you have the most severe crash scenario. In this case, you ADD the momentum of vehicle A with the momentum of vehicle B, and you get the resultant force of impact. Even if both vehicles are traveling 30 mph, with the same mass, and have a heaad-on collision, the is close to the same as one vehicle traveling 10 mph and hitting the other vehicle going 70 mph...severe impact.

When a vehicle is traveling at a constant speed one can know what?
When a vehicle is traveling at a constant speed, one can know that the forces acting on it are balanced, specifically the driving force is equal to the resistive forces like air resistance and friction. This means the net force on the vehicle is zero. Additionally, the vehicle is covering equal distances in equal intervals of time.
What are three factors that will change your vehicle's force of impact in collision?
Three factors that can affect a vehicle's force of impact in a collision are the speed at which the vehicle is traveling, the weight of the vehicle, and whether or not safety features such as seat belts and airbags are deployed and functioning properly.
What is the force of impact for a car traveling 55 miles per hour hitting a stopped vehicle?
The force of impact depends on various factors such as the weight of the vehicles, momentum, and the duration of the collision. However, in general, a car traveling at 55 miles per hour hitting a stopped vehicle can result in a significant force of impact due to the high speed involved. It is important to consider that the force of impact can cause serious damage and injuries.
At 60mph the force of your car impacting a surface is how many times as great as 30mph?
At 60mph, the force of impact is four times greater than at 30mph. This is because the force of impact during a collision increases with the square of the velocity.
What is the force of a vehicle traveling 40 mph and hitting a stationary object?
The force of impact when a vehicle traveling at 40 mph hits a stationary object depends on the mass of the vehicle and the duration of the impact. However, in general, the force can be significant due to the kinetic energy of the moving vehicle being transferred to the object upon impact. It is important to note that this force can result in damage and injury.
What is the force exerted by the wheels pushing backwards on the road?
The force exerted by the wheels pushing backwards on the road is called the frictional force. This force opposes the motion of the vehicle and is necessary for the vehicle to accelerate or decelerate. It depends on factors such as the weight of the vehicle and the coefficient of friction between the tires and the road surface.
Is it true that at 20mph the force of your car impacting surface is 4 times as great at 10mph?
No, the force of impact is not directly proportional to the speed of the car. In a collision, the force of impact is determined by the change in momentum, which is a combination of speed and mass. Doubling the speed does not necessarily mean quadrupling the force of impact.
