##### Reference no: EM13543518

A 35.0-kg seal at an amusement park slides down a ramp into the pool below. The top of the ramp is 1.80 m higher than the surface of the water, and the ramp is inclined at an angle of 30.0° above the horizontal. The seal reaches the water with a speed of 4.90 m/s. (a) What is the work is done by kinetic friction? (b) What is the coefficient of kinetic friction between the seal and the ramp?
