A 42.0 kg seal at an amusement park slides from rest down a ramp into the pool below. The top of the ramp is 1.95 m higher than the surface of the water and the ramp is inclined at an angle of 35.0 degrees above the horizontal.
A) If the seal reaches the water with a speed of 4.30 m/s, what is the work done by kinetic friction?
B) What is the coefficient of kinetic friction between the seal and the ramp?
