a block slides along a track from one level to a higher level after passing through a valley. The track is frictionless until the block reaches the higher level. On the rough surface, a frictional force stops the block in a distance d. The block's initial speed vo is 6.0 m/s, the height difference h is 1.1 m, and Uk is 0.60. Find d. (Ignore air...

A ball is thrown straight up such that it leaves your hand with 200 Joules of kinetic energy. Suppose we choose the ball + Earth as our system and we use the height of the ball when it leaves your hand as h = 0. Answer the questions below ignoring air resistance. Initial gravitational potential energy when the ball leaves your hand = Kinetic energy when the ball is half way to its maximum height = j. Gravitational potential energy...
