A ball of mass m1 = 31.00 grams moving at 15.20 m/s collides head-on with a stationary ball of mass m2 = 116.00 grams. The collision is elastic. What is the velocity of the first ball immediately after the collision?© BrainMass Inc. brainmass.com February 24, 2021, 2:09 pm ad1c9bdddf
The velocity in elastic collisions are calculated. The ball's velocity immediately after the collision is given.
