1. Will it be simply v+u.OR

2. Should this be computed using momentum conservation as follows.

Total momentum before jump = (M+m) * v

Total momentum after the jump = M * v

_{f}+ m * (u + v

_{f})

Where v

_{f}is the final velocity of the cart after the jump has been executed.

Which is the right method.
