Answer

Find height (h) using the time and acceleration due to gravity (g = 9.81 m/s^2): h = 0.5 * g * t^2

Steps

Step 1 ：Find time (t) using given information: t = 32s

Step 2 ：Calculate initial velocity (u) using known information: u = 0 m/s (ball released from rest)

Step 3 ：Find height (h) using the time and acceleration due to gravity (g = 9.81 m/s^2): h = 0.5 * g * t^2
