A small cube moves at a constant velocity v= 8.5 m/s on the smooth horizontal floor until it reaches the bottom of an inclined plane at θ = 37° above the horizontal. The cube slides up the inclined plane and covers a distance L = 2 m before leaving the incline. 

a. Calculate the velocity of the cube at the end of the inclined plane. 

b. Find the distance from the base of the inclined plane where the cube hits the a. b. floor. 

c. If the friction is not ignored, how would it change the answers to (a) and (b)?
