A 5.178 kilogram steel block is launched across a frictionless surface at 2.366 m/s, towards a 0.411 kilogram steel block initially at rest. After the impact, the smaller block goes up the scale at 13.0 degrees above the horizontal. the coefficent of static friction between the ramp and the block is us= 0.301, however the kinetic friction coefficent is yet to be determined

A)what are the velocities of each of th blocks after the collison

B) If there was no friction on the ramp, to what height (vertically) would the smaller block rise along the ramp.

C)the block rises to a height of 0.549 m above its starting position, how much work did kinetic friction do on the block
