The goal of a worker is to slide a m=20-kg crate up a L=2.5 m-long inclined at θ=25°. The worker was confident that he can do thisby giving it an initial speed of v1=4.5 m/s at the bottom and letting it go. However, the crate slides only d1 =1.7 m up the ramp, stops,and slides back down µk = 0.42 d. What is the work done by the friction force while mass is sliding down the inclined plane?e. What is the work done by the gravitation force while the mass is sliding down the inclinedplane?f. What is the kinetic energy of the mass when it just reaches the bottom of the inclined plane?
