When a superball rolls out the window...
From the top floor of a very high building, a kid drops a ball. Estimate the magnitude of the acceleration of the ball right after its collision with the ground in \(m/s^2\).
Details and assumptions
- Assume that the collision is perfectly elastic.
- The acceleration due to gravity is \(-9.8~m/s^2\).
- Do NOT neglect the effects of air resistance.
