For a car braking with constant deceleration, the time to stop is doubled when the speed of the car before braking is doubled.

A car of mass m, traveling at speed v, stops in time t when maximum braking force is applied. Assuming the braking force is independent of mass, what time would be required to stop a car of mass 2m traveling at speed v?
a car is traveling at a constant speed of Vo on a straight, level road. After the brakes are applied at t=0 seconds, the motion can be approximated by: x=t^3/100-t^2 +17t where x is the distance traveled in meters and t is the time in seconds. Determine: A the initial velocity (Vo), B. the time required for the car to stop, C. The distance required for the car to stop, and D. The maximum deceleration during braking.
PLEASE HELP!!
In coming to a stop, a car leaves skid marks 65 m long on the highway.Assuming a deceleration of 4.00 m/s2 , estimate the speed of the car just before braking.
A car is traveling with a constant speed when the driver suddenly applies the brakes, giving the car a deceleration of 3.50m/s2. The car comes to a stop in a distance of 34.0 m. What was an initial speed of the car? How long (the time) did it take for this car to stop? What was the car's speed when it had traveled 17.0 m from the point where the brakes were applied? How long did it take for this...
How much energy is dissipated in braking a 1200-Kg car to a stop from an initial speed of 30 m/s?
Two cars are driving at the same constant speed on a straight road, with car 1 in front of car 2. Car 1 suddenly starts to brake with constant acceleration and stops in 10 m. At the instant car 1 comes to a stop, car 2 begins to brake with the same acceleration. It comes to a halt just as it reaches the back of car 1. What was the separation between the cars before they starting braking?
A typical car under hard braking loses speed at a rate of about 6 m/s2. The typical reaction time to engage the brakes is 0.50 s. A local school board sets the speed limit in a school zone such that all cars should be able to stop in 5.0 m. What maximum speed does this imply for a car in the school zone?
You found the distance that you will cover while braking. You can use the expected amount of time for braking to check your answer for distance. Using the information given in the introduction and the value for distance that you found above, determine the time required for you to stop once you press the brakes. Note that the time for braking is just the time interval t3?t2. This is the information given in the introduction: You are driving down the...
An
aircraft arresting system is design is use to stop airplanes whose

An aircraft arresting system is design is use to stop airplanes whose braking system falls. If a 50 Mg airplane moving at...
Assume that the brakes in your car create a constant deceleration of 3.3 m/s2 regardless of how fast you are drivingPart A If you double your driving speed from 19 m/s to 38 m/s , does the distance required to come to a stop increase by a factor of 2 or a factor of 4? If you double your driving speed from 19 to 38 , does the distance required to come to a stop increase by a factor of...
