A 42kg seal slides down a ramp into a pool. The top of the ramp is 1.75m higher than the surface of the water, and the ramp is inclined 35 degrees above the horizontal axis. If the seal reaches the water with a speed of 4.4 m/s, (a) what is the work done by kinetic friction and (b) what is the coefficient of kinetic friction between the seal and the ramp? Thanks for the help
