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?

9. DETAILS (b) With what speed (in m/s) did she reach the floor? (Round your answer to at least three significant figures.) m/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 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.) N.S (c) with what speed (in m/s) did she leave it? (Round your answer to at least three significant figures.) m/s MY NOTES (d) To what height (in m) did she jump upon leaving the floor? m ASK YOUR TEACHER
