A runaway train car that has a mass of 14500 kg travels at a speed
of 5.8 m/s down a track.
Randomized Variables: m = 14500 kg,
v = 5.8 m/s, F = 1250 N
Part (a) What is the time required for a force
F to bring the car to rest, expressed in terms of
m, v, and F?
Part (b) Compute this time, in seconds, for a
force of 1250 N.

A mini train is moving at a constant speed along a straight, horizontal track. The train consists of an engine, which is in front, and one car that is being towed by the engine by a cable. The engine and car are not touching. There is a coefficient of kinetic friction of between the engine and the track, and between the car and the track. The coefficient is the same for both; it is 0.100. The engine has a mass...

A 1036 kg mass car travels on a straight flat road at a constant speed v1 = 39.2 m / s. When the driver sees a police radar ahead of him, he takes his foot off the accelerator. After 14 s, the car speed is v2 = 26.7 m / s less than the speed limit for that stretch of road. The module of the average force that acted on the car in the interval of 14 s is Choose...
