Starting from rest, a 68.0 kg woman jumps down to the floor from a height of...

Starting from rest, a 68.0 kg woman jumps down to the floor from a height of 0.650 m, and immediately jumps back up into the air. While she is in contact with the ground during the time interval 0 < t < 0.800 s, the force she exerts on the floor can be modeled using the function

F = 9,200t − 11,500t²

where F is in newtons and t is in seconds.

(a) What impulse (in N · s) did the woman receive from the floor? (Enter the magnitude. Round your answer to at least three significant figures.)

b. With what speed (in m/s) did she reach the floor? (Round your answer to at least three significant figures.)

(c) With what speed (in m/s) did she leave it? (Round your answer to at least three significant figures.)

d To what height (in m) did she jump upon leaving the floor?
