Reference no: EM13301770

Gerri leaves the long jump takeoff board with a vertical velocity of 4 m/s and a horizontal velocity of 8 m/s.

a. What is Gerri’s horizontal velocity just before she lands?

b. If Gerri is in the air for 0.85 s, what is her horizontal displacement during this time in the air?

c. What is Gerri’s vertical velocity at the end of her 0.85 s flight?

d. If Gerri’s center of gravity was 1.0 m high at the instant of takeoff, how high will it be at the peak of her flight?
