A 1kg ball moving at 12 ms collides head
on with a 2kg ball moving in the opposite
direction at 24 m/s. The velocity of each ball
after the impact, if the coefficient of restitution
is 2/3, is
1) -28m/s; 4 m/s 2) -20 m/s; 4 m/s
3) 20 m/s; 24 m/s 4) 28m/s, 4m/s
A ball impings directly upon another ball at solution
