Two basketballs of equal mass collide in midair. If the initial velocity of Basketball A was to the right at 2.5 m/s and the initial velocity of Basketball B was to the left at 1.7m/s, what is the final
velocity of Basketball A if the collision is perfectly elastic?*

1.7 m/s to the left
1.7 m/s to the right
2.5 m/s to the left
25 m/s to the right

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j ?
