DETAILS 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.) N s Starting from rest, a 60.0 kg woman jumps down to the floor from a height of 0.750 m, and immediately jumps back up into the air. While she 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 (b) With what speed (in m/s) did she reach the floor? (Round your answer to at least three significant figures.) m/s MY NOTES (c) With what speed (in m/s) did she leave it? (Round your answer to at least three significant figures.) m/s ASK YOUR TEACHER
