Question

How will you investigate a change in velocity affects the velocity of the two carts after the collision if the objects do not stick together?

Answer 1

P = mv

This is a momentum question:

Momentum is always conserved so the momentum before and after a collision must be equal so:

The velocity of the two objects after they collide and dont stick together if no KE is lost is dependent on the mass of each of the objects by:

$m_{1} v_{1i} + m_{2} v_{2i} = m_{1} v_{1f} + m_{2} v_{2f}$

Where i is initial and f is final meaning before and after the collision
