A 0.380 kg ball is shot directly upward with an initial speed of 38.5 m/s. What is its angular momentum about point P, at a horizontal distance of 1.85 m from the launch point, when the ball is at its max height? Halfway back to the ground? What is the torque on the ball about point P due to the gravitational force when the ball is at its max height? Halfway back to the ground? Where should I begin?
