Submit answer
5.
Starting from rest, a 67.0 kg woman jumps down to the floor from a height of 0.710 m , and immediately jumps back up into the air. While she is in contact with the ground during the time interval F=9,200t-11,500t2FtN*sN*smsmsmsms0, the force she exerts on the floor can be modeled using the function
F=9,200t-11,500t2
where Fisin newtons and tisin seconds.
(a) What impulse (inN*s) did the woman receive from the floor? (Enter the magnitude. Round your answer toat least three significant figures.)
N*s
(b) With what speed (inms) did she reach the floor? (Round your answer toat least three significant figures.)
ms
(c) With what speed (inms) did she leave it?(Round your answer toat least three significant figures.)
ms
(d)To what height (inm) did she jump upon leaving the floor?
m
