Homework Answers
Concept - Find the frictional force acting on the box. According to work energy theorem, the work done by friction and gravity and the spring will be collectively equal to the change in kinetic energy. The final kinetic energy will be zero because the block stops at maximum compression.

A 20 kg crate is allowed to slide down a 60-m long smooth inclined plane which is 30° with the horizontal. At the bottom of the inclined plane, the crate is allowed to slide horizontally with the ground where the coefficient of friction between the crate and the ground is 0.15. After 1 m, the crate would meet a coil with a spring constant of 1000 N/m. (Assume that the friction no longer acts as the crate hits the spring).Calculate...
