A block of mass m is on an inclined ramp. The ramp makes anangle θ with respect to the horizontal, as shown. The ramp hasfriction, with coefficient of kinetic friction μk and static friction μs.This experiment takes place on earth.The block has an initial speed of v up the ramp. It travels adistance d along the ramp before it stops.Answer using variables, please d) Calculate the work done by the Friction force as the block travels the distance d.Is it positive, negative, or zero?e) If the block comes to rest, how far has it travelled?Use the work-energy principle and your results of parts b), c), and d).f) Briefly (one sentence) explain why this problem could not be solved using conservation ofenergy.

A block of mass 2 kg is initially at rest on a frictionless surface. A force of 10 N is applied to the block for a distance of 5 meters along the horizontal direction. Calculate the work done on the block and the final kinetic energy of the block. (Note: In this question, assume the force is constant and applied parallel to the displacement of the block.) Take acceleration due to gravity as 9.8 m/s².
