Picture taken from problem 13-35. A 2000 kg truck is traveling at 25 meters/second. The driver suddenly hits the brakes, causing the truck to slide on the road. The coefficient of friction between the truck and the road is fk = 0.32. Determine the distance the truck slides. (Notice: the box is irrelevant in this problem)

A 10 kg box is pushed from rest by a truck for 2m. Once the truck stops pushing the box it is traveling 6 m/s.This box slides for 5 seconds before coming to a stop. If the specific heat is 2 joules per degree kg, how much did the temperature of the box change by and what is the average force applied by the truck?

A truck is traveling down a road with a 4 percent grade at a speed of 87 mith when its brakes are applied to slow it down to 24.5 mih, An arriskid braking system imits the braking force to a value at which the wheels of the truck are just about to slide. Knowing that the coefficient of static friction between the road and the wheels is 0.60, determine the shortest time needed for the truck to slow down. (Round...

A truck with a mass of 1510 kg and moving with a speed of 14.5 m/s rear-ends a 671 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second. m/s vcar truck m/s
