At Sea World, a 32.0-kg seal slides down aramp into the pool below. The top of the ramp is 1.75 m higher than the surface of the water, and theramp is inclined at an angle of 30.0° above the horizontal. Theseal reaches the water with a speed of 4.90 m/s.

J
(b) What is the coefficient of kinetic friction between the sealand the ramp?
