a rock weighing 20.0N falls from a height of 16.0m and sinks 0.600 m into the ground. from energy considerations, find the average force between the rock and the ground as the rock sinks.

(avg. force) x (distance sunk) is the3 work done by the soil in decelerating the rock
That = (kinetic eneregy whem it hits ground) = M g H

M g = 20 N

Avg force = (20 N)*(H/X)
H = 16 m and X = 0.60 m

1 answer

533.33 N
