At Sea World, a 36.0-kg seal slides down aramp into the pool below.The top of the ramp is 1.55 m higher than the surface of the water,and theramp is inclined at an angle of 30.0° above the horizontal.Theseal reaches the water with a speed of 4.90 m/s.
(a) What is the work is done bykineticfriction?
(b) What is the coefficient of kinetic friction between the sealandthe ramp?
