A 43.0kg seal at an amusement park slides from rest down a ramp into the pool below. The top of the ramp is 1.75m higher than the surface of the water and the ramp is inclined at an angle of 35.0 ?above the horizontal.

A.) If the seal reaches the water with a speed of 4.40 m/s, what is the work done by kinetic friction?

B.) What is the coefficient of kinetic friction between the seal and the ramp?
