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?(1 point) Responses
When it was empty, the cart had less kinetic energy
The cart’s kinetic energy depends on Mr. Starr’s mass.
The cart had the same kinetic energy going each way.
When it was full, the cart had less kinetic energy.
