An object of mass 10 kg is released at point A, slides to the bottom of the 30° incline, then collides with a horizontal massless spring, compressing it a maximum distance of 0.75 m. (See below.) The spring constant is 500 M/m, the height of the incline is 2.0 m, and the horizontal surface is frictionless. 

(a) What is the speed of the object at the bottom of the incline? 

(b) What is the work of friction on the object while it is on the incline? 

(c) The spring recoils and sends the object back toward the incline. What is the speed of the object when it reaches the base of the incline? 

(d) What vertical distance does it move back up the incline?
