Solve the all parts of given question:

Question: A 4.75kg block starts at the top of a 13.6m long incline that has an angle of 10 degree to the horizontal. The block then slides out on a horizontal frictionless surface and collides with a 7.11 kg block in an inelastic collision in which the blocks stick together. The blocks then slide to the right onto a frictional section of track as a result of the collision.

Part I: How much Kinetic Energy was lost in the collision?

Part II: How far do the blocks slide to the right on the frictional surface before stopping if the coefficient of kinetic friction is µk = 0.18.

I need tutor help to solve the above question. Thanks in advance.
