Starting from rest, a 57.0 kg woman jumps down to the floor from a height of 0.740 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 = 9,200 t − 11,500 t 2 where F is in newtons and t is in seconds. With what speed (in m/s) did she leave it? (Round your answer to at least three significant figures.
