WebApr 21, 2024 · Just using these two measurements, I can find the rebound ratio. Using the geometric sequence formula, we have 111=200(r)(2−1). 200 represents the initial height, and (2, 111) represents the second height after the first bounce at 111 cm. We now know that this ball has a 55.5% rebound ratio. What is rebound height? WebIn terms of masses and velocities, this equation is. m1v1x + m2v2x = m1v ′ 1x + m2v ′ 2x. 8.3. But because particle 2 is initially at rest, this equation becomes. m1v1x = m1v ′ 1x + m2v ′ 2x. 8.4. The components of the velocities along the x -axis have the form v cos θ .
