A block of mass 7.82 kg is sliding to the right along a frictionless surface at v = 1.50 m/s as shown below.?

A block of mass 7.82 kg is sliding to the right along a frictionless surface at v = 1.50 m/s as shown below.?



A) How fast will the block be moving at point A, at the bottom of the left ramp? 
B) How far up the right ramp will the block go? 
C) Now a rough patch of length 2.75 m is created at point B. This patch is characterized 
by µs = 0.47 and µk = 0.12 . If we restart the block, identically as before, what will the 
speed of the block at point C be? 
D) How far up the right ramp will the block go now?
