In the figure, a 0.400 kg ball is shot directly upward at initial speed 35.4 m/s. What is its angular momentum about P, 8.69 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? The sign convention is that a torque is positive if it would cause counterclockwise rotation. (a) Number i (b) Number i (c) Number i (d) Number i Units Units Units Units -Ball !! x
