Chapter , Problem 102(choose chapter or problem)
A 285-kg stunt boat is driven on the surface of a lake at a constant speed of toward a ramp, which is angled at above the horizontal. The coefficient of friction between the boat bottom and the ramps surface is 0.150, and the raised end of the ramp is above the water surface. (a) Assuming the engines are cut off when the boat hits the ramp, what is the speed of the boat as it leaves the ramp? (b) What is the speed of the boat when it strikes the water again? Neglect any effects due to air resistance.
