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 0.390 m . What is its initial velocity v0 as it leaves the ground?

Expert Answer

Answer

Given acceleration due to gravity = a= 9.8m/s2

distance (maximum height) = 0.390m

Final velocity= V1= 0

Inital velocity = V0= ?

Using the equation V1²=V0²+2* a* s

0= V0² + 2*(-9.8 m/s2) * (0.390 m)

V0² = 7.644 m²/s²

V0= 2.765 m/s

Hence the initial velocity is 2.765 m/s as it leaves the ground.
