Two 0.50-kg carts, one red and one green sit about half a meter apart on a low-friction track. You push on the red one with a
constant force of 4.0 N for 0.17 m and then remove your hand.
The cart moves 0.33 m on the track and then strikes the green
cart. What is the work done by you on the two cart system?​
