In this problem, you will apply kinematic equations to a jumping flea. Take the magnitude of free$-$fall acceleration to be 9.14 m$/$s$2$ $.$ Ignore air resistance.

 A flea jumps straight up to a maximum height of 0.665 m$.$ The initial velocity v$0$ as it leaves the ground is 4.12 so How long is the flea in the air from the time it jumps to the time it hits the ground?
