QuestionQuestions 12-14: In a physics lab, a student uses three light, frictionless wheeled carts as shown to the right. Each cart is loaded with blocks of equal mass.
12. The same force $F$ is applied to each cart and they move equal distances $d$. In which one of these three cases is more work done by force F? a) cart 1 b) cart II c) cart III d) the same work is done on each cart
13. The same force $F$ is applied, to each cart and they move equal distances $d$. Which cart will be moving the fastest at the end of distance $d$ ? a) cart 1 b) cart II c) cart Ill d) all three will have the same kinetic energy
