ignoring air resistance?
V^2=2gh
2nd part:
1/2 m vf^2+frictionforce*h=mgh
solve for frictionforce
A 143-g baseball is dropped from a tree 13.0 m above the ground.
With what speed would it hit the ground if air resistance could be ignored?
If it actually hits the ground with a speed of 8.00 m/s , what is the magnitude of the average force of air resistance exerted on it?
