Problem 8-34 Elastic collision - Part 3 - A
A superball of mass \(22\; g\) rolls with a speed of \(3.5\; m/s\) toward another (stationary) superball of mass \(27\; g\). If the balls have a head-on elastic collision, what are the velocities magnitudes and directions) of the balls after the collision?
[Ans. \(3.1\; m/s\) forward and \(0.4\; m/s\) backward]
Accumulated Solution
\(m_1\; v_1 = m_1\; v{_1}'+ m_2\; v{_2}'\)
No. Elastic means that \(E_K\) is conserved.
