Maximizing Impulse

APPH12-LUYNUC

Two carts collide. The one on the left has a mass, ${ M }_{ 1 }$ and moves with velocity $v$ to toward the right.

In which scenario below is the maximum impulse given to the second cart with mass ${ M }_{ 2 }$?

A

The impulse will be maximized if the two carts stick together and move to the right.

B

The impulse will be maximized if ${ M }_{ 1 }$ bounces back to the left with a speed close to $v$.

C

The impulse will be maximized if ${ M }_{ 1 }$ does not stick to ${ M }_{ 1 }$, but moves to the right with a lower speed than $v$.

D

The impulse will be maximized if ${ M }_{ 1 }$ does not stick to ${ M }_{ 2 }$, but moves to the right with a higher speed​ than $v$.
