To calculate the average acceleration of the golf ball, we can use the following formula:
acceleration = (final velocity - initial velocity) / time
In this case, the initial velocity of the golf ball is 0 m/s since it was dropped from rest. The final velocity is 14.7 m/s, and the time taken is 1.5 seconds.
Plugging these values into the formula, we have:
acceleration = (14.7 m/s - 0 m/s) / 1.5 s acceleration = 14.7 m/s / 1.5 s acceleration = 9.8 m/s²
Therefore, the average acceleration of the golf ball is 9.8 m/s².
