dynamics of rigid bodies

10. The flatbed truck is traveling at constant speed of 60 kph up the 15% grade when the 100 kg crate which it carries is given a shove which imparts to an initial relative velocity x = 3m/s towards the rear of the truck. If the crate slides a distance x = 2 m measured on the truck bed before coming to rest on the bed.

A. Compute the acceleration of the block.
B. Compute the coefficient of kinetic friction between the crate and the truck.
C. How long did it take for the crate to move a distance of 2 m.
