In this problem, you will apply kinematic equations to a jumping flea. Take the magnitude of free-fall acceleration to be 9.80m/s2. Ignore air resistance.

A flea jumps straight up to a maximum height of 0.460m. What is its initial velocity v0 as it leaves the ground?

Lincoln · Answer 1

V o - initial velocity

v = velocity at the maximum height,

v² = v o² - 2 g h

v = 0

0 = v o² - 2 g h

v o² = 2 g h = 2 · 9.80 · 0.460

v o² = 9.052

v o = √9.052 = 3.004197 m/s ≈ 3 m/s
