1. The problem statement, all variables and given/known data In the figure, a 0.400 kg ball is shot directly upward at initial speed 40.4 m/s. What is its angular momentum about P, 6.65 m horizontally 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 P due to the gravitational force when the ball is (c) at maximum height and (d) halfway back to the ground? 2. Relevant equations p=mv l=r x p 3. The attempt at a solution im stuck at part b, i used l=rxp but not sure if i did that right.
