When the ball with a mass of 1kg is released freely from 3m, the resistance of the ball is 0.1 times of the gravity The ball with a mass of 1kg is released freely from 3m. The resistance of the ball in motion is 0.1 times that of gravity. Assuming that the ball does not lose mechanical energy when colliding with the ground, the path of the ball from the beginning to the final rest is determined

The resistance of the ball in motion is 0.1 times that of gravity. Assuming that the ball does not lose mechanical energy when colliding with the ground, the path of the ball from the beginning to the final rest is determined

The reduction of mechanical energy E = MGH from initial release to final rest
From the principle of function
MGH = work to overcome resistance w
Let the distance be s
W=fS=0.1mg*s
So MGH = 0.1mgs
S=10h=10*3=30m
