Physics

A 0.20 kg maroon ball is dropped vertically from rest from 1.5m on to the soft ground. It sinks 0.05m into the ground while stopping

1) What quantities can you determine before the ball hits the ground? (Don't have to determine, just list)

2)What quantities can you determine after the ball hits the ground? (Don't have to determine, just list)

3)Calculate any forces on the ball for the time just after it contacts the ground until it stops.

Answer in regards to force (etc gravitational force, frictional force, net force) not work, potential energy and kinetic energy
