Then, the block starts to climb the rough ramp. As it climbs, it loses kinetic energy due to the work done against gravity and friction. The work done against gravity is mgh, where h is the height the block climbs. The work done against friction is the force Show more…

A small block of mass m slides to the left on a frictionless horizontal surface with speed v. Then, the block slides up a rough ramp that has an incline angle of α. The coefficient of kinetic friction between the ramp and box is μ. The acceleration due to gravity is g. What is the height h of the block when its speed up the ramp equals cv, where 0 < c < 1? h = v^2(1 - c^2) / (2g(1 + μ cot(α)))

A box of mass m is initially at rest at the top of a ramp that is at an angle of ̘ with the horizontal. The block is at a height h and length L from the bottom of the ramp. The block is released and slides down the ramp. What is the acceleration of the block as it slides down the ramp? The coefficient of kinetic friction between the block and the ramp is μ.
