Assume that a car is moving behind a loaded truck. Both moving with the same uniform velocity. A box from the top of the truck falls. Does car hit the box before the box hits the road, if driver neither brake nor accelerate ?

A 20kg box rests on the flat floor of a truck. The coefficients of friction between box and floor are mu_(s) = 0.15 and mu_(k) =0.10. The truck stops at a stop sign and then starts to move with an acceleration of 2 m/s^(2) . If the box is 2.2 m from the rear of the truck when the truck starts, how much time elapses before the box falls of fthe rear of the truck? How far does the truck travel in this time.

A large truck and a car is moving with same velocity have a head on collision. Which of the following is an incorrect statement?

A car of mass one metric ton travelling at 32m//s c dashes into the rear of a truck of mass 8000kg moving in the same direction with a velocity of 4m//s After the collision the car bounces back wards with a velocity of 8m//s What is the velocity of the truck after the impact ?

A truck and a car are moving with equal velocity. On applying the brakes both will stop after certain distance, then

A motor cycle and a car are moving on a horizontal road with the same velocity. If they are brought to rest by the application of brakes, which provided equal retarding forces, then

A motor car moving at a speed of 72 km //h can not come to a stop in less than 3.0 s while for a truch this time interval is 5.0s On a highway the car is behind the truck both moving at 72 km //h The truck geives a signal that it is going to stop at emergency. At what distance the car should be from the truck so that it does bot bump onto (collide with) the truck. Human responde time id 0.5 s .

A truck and a car moving with the same KE are brought to rest by the application of brakes which provide equal retarding force. Which of them will come to rest in a shorter distance ?

A turck is moving on the ground with a velocity v=12m//s and a box is moving on the truck with respect to it with a velocity u=5m//s as shown in the figure. What is the velocity of the box with respect to the ground?
