A student wanted to investigate changing the mass of a cart that you can push. The student pushed both carts with a force of 200 Newtons. If one cart has a mass of 100kg and the other cart a mass of 50kg, what results would the student expect to see as far as how fast each cart moved in comparison with one another? Explain in 2 sentence's.
1 answer
The student would expect to see the cart with a mass of 50kg move faster than the cart with a mass of 100kg. This is because according to Newton's second law of motion, the acceleration of an object is inversely proportional to its mass. Therefore, the cart with a smaller mass would experience a greater acceleration and move faster.
