A 116 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.

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

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

a) , b)

Explanation:

The seal is modelled after the Principle of Energy Conservation and the Work-Energy Theorem:

a) The work done by the kinetic friction is:

b) The coefficient of kinetic friction is:

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

answer; equivalent to a one(1) horsepower motor;
