The instant when the ball is released is considered to be the initial time t = 0. The position of the ball along the ruler is described by the variable y. The position of the ball at a time t is given by y(t) = y 0 + v 0t+ 1 2 gt2: (1) If the ball is released from rest, the initial velocity is zero: v 0 = 0. Therefore, y(t) = y 0 + 1 2 gt2: (2) 1
