I know how to get the final velocity but how long does it take to accelerate to that velocity from zero?

Does it depend on the elasticity of the materials?

I guess we need to know long did the transfer of energy take??

For example a 3kg stationary ball is hit by a 1kg ball moving at 15m/s, transferring all of its energy into the the stationary ball.

The 3kg ball will end up moving at 5m/s.

But how fast did it accelerate?
