1. If there is an equal amount of force on both sides of the tug of war cart, the cart will not move. This is because the forces on either side of the cart cancel each other out, resulting in a net force of zero.
2. 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 the acceleration of an object is inversely proportional to its mass, according to Newton's second law. Since both carts experience the same force of 200 Newtons, the cart with less mass will experience a larger acceleration and therefore move faster.
3. To move the bowling ball to reach 15 mph, the scientist would have to exert a larger force on the ball compared to the golf ball. This is because the momentum of an object is directly proportional to its mass and velocity. Since the bowling ball is much heavier than the golf ball, it requires a greater force to achieve the same velocity.

2. 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?
