Question

If two identical balls moving in opposite directions with equal speed collide and stick to each other what is the velocity after collision and why?

Answer 1

Answer:

Zero

Explanation:

If the balls with the same mass collide at the same speed,the transfer of momentum would put pressure on both the balls,as the mass and speed is the same, lets say the balls are moving at 1 metre per second, on both the sides,on collision,the the velocity would be Zero.
