In this problem, you will apply kinematic equations to a jumping flea. Take the magnitude of free-fall acceleration to be 9.80 m/s2 . Ignore air resistance.
A flea jumps straight up to a maximum height of 0.450 m . What is its initial velocity v0 as it leaves the ground?
How long is the flea in the air from the time it jumps to the time it hits the ground?
Maximum height reached by the flea is
Initial velocity of flea
Final velocity of flea at the maximum height is
Acceleration of the flea is
Using kinematic equation,
Initial velocity of flea is
---------------------
Using kinematic equation
Vertical distance covered by flea (going up and coming down) is zero,
The flea is in air for a time of before it hits the ground.
