What peak height does brian’s center of gravity achieve

Reference no: EM13301771

Brian is attempting to high jump over a crossbar set at 2.13 m (7.0 ft). At the instant of takeoff (when he is no longer in contact with the ground), his vertical velocity is 4.0 m/s, and his center of gravity is 1.25 m high.

a. What is Brian’s vertical acceleration at the instant of takeoff?

b. How much time elapses after takeoff until Brian reaches his peak height?

c. What peak height does Brian’s center of gravity achieve?
