problem 1) In this problem, you will apply kinematic equations to a jumping flea. Take the magnitude of free-fall acceleration to be 9.80m/s^2 . Ignore airresistance.

1. A flea jumps straight up to a maximum height of 0.510m . What is its initial velocity as it leaves the ground?
3.16m/s

2. How long is the flea in the air from the time it jumps to the time it hits the ground?
time in air=____s

i just need question #2

Problem 2) A rock is thrown vertically upward with a speed of 19.0 {rm m/s} from the roof of a building that is 50.0 {rm m} above the ground. Assume free fall.1. In how many seconds after being thrown does the rock strike the ground?t=___s2. What is the speed of the rock just before it strikes the ground?Vground=_____m/si dont get this problem...
