Homework Help: physics

Posted by jane on Saturday, June 13, 2009 at 7:28pm.

A 0.400 kg ball is shot directly upward at initial speed 40.0 m/s. What is its angular momentum about a point 2.0 m horizontal from the launch point, when the ball is a) at maximum height and b) halfway back to the ground? What is the torque on the ball about the point 2m from the horizontal launch point due to the gravitational force when the ball is c) at maximum height and d) halfway back to the ground?

I know that because max height is v=0, there is 0 angular momentum, but i can't figure out the rest
