A ball is rolled twice across the same laboratory table and allowed to roll off the table and strike the floor. In each trial, the time it takes the ball to travel from the
edge of the table to the floor is accurately measured. (Ignore friction.)
a. In trial A, the ball is traveling at 2.5m/s when it reaches the edge of the
table. The ball strikes the floor 0.391 second after rolling off the edge of
the table. Calculate the height of the table. (Show all work, including the
equation and substitution with units.)
