Question

A box (mass = 100 g) is initially connected to a compressed (x = 80 cm) spring (? = 100 N/m) at point A. It was released and started moving along the horizontal surface (µk = 0.2) until it moves up along the inclined surface (µk = 0.3). The box then stops at point D alone the incline. Consider that e = 30 m and θ = 30.

Kindly answer only a and b. Please include necessary FBD for each item. 
(a) What is the velocity of the box at point B?) (Ans: 25.24 m/s)
(b) What is the change in kinetic energy from point B to point C? (Ans.: −5.88 J)
