Unformatted text preview: v o = 40.0 m/s. Then with y = 1 2 y max , Eq. 216 can be used to give v = v o / 2 . In this way we arrive at L = 22.6 kg . m 2 /s. (c) As mentioned in the previous part, we use the minus sign in writing = r F with the force F being equal (in magnitude) to mg . Thus, = 7.84 N . m. (d) Due to the way r is defined it does not matter how far up the ball is. The answer is the same as in part (c), = 7.84 N . m....
