Mr.starr pushed a cart full of groceries to his car after emptying the cart,he pushed it back to the store he pushed the cart at a speed of 2 meters per second each way which is the best prediction
when it was empty the cart had less kinetic energy

the cart had the same kinetic energy going each way
the carts kinetic energy depends on mr.starr's mass
I think that its b am I right?
