Question
A ball slides off a table of height h = 1.1 m as shown below. Use the law of conservation of mechanical
energy to find the speed of the ball when it reaches the floor. The initial speed of the ball is zero. Note
that the mass of the ball is not important, so calculate everything per unit of mass, or, if it helps, pick any
convenient value for the ball's mass, for example, m 1 kg (show that it does not change the answer!).
