39PRACTICE PROBLEM
A group of students experimented on objects falling from rest. They dropped a bowling ball of mass 5.2 kg from 110 m above the ground into the sand. After reaching the ground, the bowling ball sank 0.59 m deep into the sand before stopping. If the terminal velocity of the bowling ball was 32 m/s, calculate the average force the sand exerted on it that eventually made it stop.
