In Figure a block is released from rest at height d = 40 cm and slides down a frictionless ramp and onto a first plateau, which has length d and where the coefficient of kinetic friction is 0.50. If the block is still moving, it then slides down a second frictionless ramp through height d/2 and onto a lower plateau, which has length d/2 and where the coefficient of kinetic friction is again 0.50. If the block is still moving, it then slides up a frictionless ramp until it (momentarily) stops. Where does the block stop? If its final stop is on a plateau, state which one and give the distance L from the left edge of that plateau. If the block reaches the ramp, give the height H above the lower plateau where it momentarilystops.

Dion is an engineer with Tesla Motors who helps to design electric motors. It has always been his dream to start his own business, but as he has gotten older, he has not gotten around to it. He is also an avid cyclist who rides near his home in Palo Alto, California. It is hilly terrain and as he...
A stone with a weight of 5.29 N is launched vertically from ground level with an initial speed of 20.0 m/s, and the air drag on it is 0.265 N throughout the flight. What are? (a) The maximum height reached by the stone and (b) Its speed just before it hits the ground?
A particle can slide along a track with elevated ends and a flat central part, as shown in Figure. The flat part has length L = 40cm. The curved portions of the track are frictionless, but for the flat part the coefficient of kinetic friction is µ k = 0.20. The particle is released form rest...
