Impulse and Momentum

Impulse Physics


<div class="wp-block-create-block-problemblock">A 2kg car is traveling east at 3 m/s and a 4kg car is traveling west at 6 m/s.  Now assume the cars bounce off each other in a perfectly elastic collision.  The final velocity of the 2kg car is -4 m/s.  Find the direction and velocity of the other car after the collision.</div>
