At Sea World, a seal of 34.0 kg slides down the ramp into the pool beneath. The top of the ramp is 1.65 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 having a speed of 4.90 m/s.
(i) Determine the work is done through kinetic friction?
(ii) Find out the coefficient of kinetic friction among the seal and the ramp?
