Force = Mass x Acceleration
Initial speed of car = 0, Final speed = 40 feet/sec in time 2 seconds
Acceleration = (v-u)/t = (40 - 0)/2 = 20 feet/sec/sec
Force = 3500 x 20 = 70000 pounds/sec/sec

What is your 100 meter time converted from 9.90 for 100 yards?
10.0 and 9.9 seconds is not the same thing when accuracy is needed, not rounded off numbers. 10.0 and 9.9 seconds is not the same thing when accuracy is needed, not rounded off numbers. 10.0 and 9.9 seconds is not the same thing when accuracy is needed, not rounded off numbers.
How many seconds are needed by a car whose speed is 40 km hr to cover a distance of 8 km?
12 minutes = 720 seconds
How fast would your mile be if you ran 8 miles in 4 minutes and 31 seconds?
Velocity = Distance ÷ Time. BUT : we need to ensure the measurements used are converted (if needed) to provide a sensible answer. If the answer is required in miles per hour (mph) then the distance of 8 miles is fine but the time of 4 minutes 31 seconds needs to be converted into hours. 31 seconds = 31/60 minutes = 0.516667 mins 4.516667 mins = 4.516667/60 hours = 0.075278 hours Then 8 ÷ 0.075278 = 106.27mph (2dp)
What are three components needed to find an object acceleration?
Using the definition of acceleration as change of speed / time, you basically need to know: * A time interval during which the object accelerates. * The velocity at the beginning of this time interval. * The velocity at the end of this time interval.
A weight on the end of a spring bobs up and down one complete cycle every 2 seconds its period is?
We clearly heard you say "one complete cycle every 2 seconds". That means that the period is 2 seconds. No calculation or arithmetic of any kind is needed.

What is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 m s?
The only factor needed to calculate change in velocity due to acceleration of gravity is time. The formula to calculate the change in velocity is: change in velocity = acceleration due to gravity * time.
Suppose the force of friction on a sliding object is 10N. what is the force needed to maintain a constant velocity is?
To maintain a constant velocity, the force needed to overcome the frictional force must be equal in magnitude but in the opposite direction. Therefore, a force of 10N is needed to maintain the constant velocity of the sliding object.

What is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 ms?
What two pieces of information is needed to make change?
Speed and velocity
What type of force is needed to change the velocity of object?

What is the only factor needed to calculate change in velocity due to acceleration of gravity (9.8 m/sĀ²)?
?Initial velocity?
What is the relationship between the mass and the velocity of a whirling object?
The mass and velocity of a whirling object are directly related. As the mass of the object increases, more force is needed to maintain the velocity, leading to an increase in velocity. Conversely, decreasing the mass decreases the force needed and therefore the velocity decreases.
What is the minimum stream velocity needed to carry a particle of sand?
The minimum stream velocity needed to carry a particle of sand depends on the size and weight of the sand particle, as well as the characteristics of the stream such as flow rate and turbulence. In general, for typical sand particles, a stream velocity of around 0.3 m/s to 1 m/s is needed to entrain and transport them.
What is the approximate minimum stream velocity needed to move a particle with a diameter of a 6.4 moving?
The approximate minimum stream velocity needed to move a particle with a diameter of 6.4 can be determined using the equation for the critical velocity of sediment transport. For a particle of this size, the critical velocity is typically around 0.3-0.4 m/s in most natural streams and rivers.
