A 25 kilogram seal at an amusement park slides down a ramp into the pool below. The top of the ramp is 1.60 meter higher than the surface of the water, and the ramp is inclined at an angle of 30 degree above the horizontal. The seal reaches the water with a speed of 4.90 meter per second.
Determine the work is done by kinetic friction?
Find the coefficient of kinetic friction between seal and ramp?
