A 117 kg seal at an amusement park slides from rest down a ramp into the pool below. The top of the ramp is 1.85 m higher than the surface of the water and the ramp is inclined at an angle of 26.5 ∘ above the horizontal.

If the seal reaches the water with a speed of 4.10 m/s, what is the work done by kinetic friction?

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