What else can I help you with?
A 1500 kg car travels at 90 kph along a straight concrete highway Faced with an emergency situation the driver jam what will be the car?
If the driver jams on the brakes, the car will begin to decelerate rapidly. The force of deceleration will depend on the braking system's efficiency and the road conditions. If the brakes are effective, the car will come to a stop, but the stopping distance will vary based on factors like friction and the initial speed. In this scenario, the car's momentum will convert to kinetic energy, which the brakes must dissipate to bring the car to a halt.
How plane is steered on ground?
Some airplanes are always steered by the rudder Some are steered by a tail wheel coupled to the rudder Some are steered by the brakes at low speed some are steered by the nose wheel at low speed by a tiny steering wheel on the instrument panel All (almost) airplanes have the ability to steer with the brakes
What relationship could be represented by a graph with a negative slope?
something which decreases over time e.g. speed of a car when the brakes are applied. Time on the x-axis and speed on the y-axis of the graph
What happens when you step on the brakes math algebra?
When you step on the brakes of a vehicle, you apply a force that increases the deceleration of the car, which can be represented mathematically using the equation ( a = \frac{F}{m} ), where ( a ) is acceleration (or deceleration), ( F ) is the force applied by the brakes, and ( m ) is the mass of the vehicle. This force results in a negative acceleration, causing the vehicle's speed to decrease over time. The relationship between speed, time, and distance can also be described using the equations of motion, allowing you to calculate how far the vehicle will travel before coming to a stop.
What would be the total stopping distance at a speed of 60 miles per hour?
The stopping distance, after decelerating from 60 mph to 0 mph, will depend on the efficiency of the brakes, the friction between the tyres and the road surface and the mass of the vehicle.The initial speed alone cannot give you an answer.
How much thermal energy is generated by the brakes of a kg train in causing the train to slow from a speed of W sec to speed of W sec?
The amount of thermal energy generated by the brakes of a train in slowing down from one speed to another depends on the mass of the train, the initial and final speeds, and the efficiency of the braking system. The energy is converted from the kinetic energy of the train into heat energy by the brakes. The specific calculation would require more details about the system.
What affects speed?
the brakes affect the speed
What are the best braking options for a single speed bike with single speed bike brakes?
The best braking options for a single speed bike with single speed bike brakes are typically caliper brakes or cantilever brakes. These types of brakes provide reliable stopping power and are commonly used on single speed bikes. It is important to regularly maintain and adjust these brakes to ensure optimal performance and safety while riding.
If you are applying the brakes on your bicycle are you accelerating explain?
Using brakes slows your speed.
What are the advantages of single speed brakes compared to other types of brakes?
Single speed brakes, such as coaster brakes or rim brakes, have advantages like simplicity, low maintenance, and cost-effectiveness compared to more complex braking systems like disc brakes. They are easy to use and repair, making them a popular choice for casual riders or those on a budget.
Does the Space Shuttle have speed brakes?
The Space Shuttle orbiter has speed brakes in the tail which open up when it's going to land and also has a parachute brake system which is deployed upon touchdown in addition to its wheel brakes.
What should you do if your brakes become wet?
While driving, apply the brakes gently for a short distance, as you maintain your speed.
Does a one speed bike have brakes?
Most do, but not all. Real track bikes, and some types of BMXes won't have brakes.
Is stepping on the brakes of a moving train an example of acceleration?
No, stepping on the brakes of a moving train is an example of deceleration, as it is the action of slowing down or reducing the speed of the train. Acceleration refers to an increase in speed or velocity.
What if brakes squeak only at low speed?
all ou must do is always stay on high speed.
Why a train moving at high speed comes to halt when chain is pulled from some compartment?
When the chain is pulled, it activates the emergency brakes on the train, causing it to gradually come to a halt. The emergency brakes are designed to bring the train to a stop as quickly and safely as possible to prevent accidents or emergencies on board. This allows the train to stop efficiently even when it is moving at high speed.
Suppose that you are in a moving car and the motor stops. You step on the brakes and slow the car to half speed. If you release your foot will the car speed up or continue at half speed or slow down?
Assuming you are not pressing down on the gas, when you release the pedal, the car will slow down over time and evetualy come to a stop. Unless you are going down a hill, in which case you will speed up.
