a large truck collides head-on with a small compact car. during the collision:
1. A large truck collides head-on with a small compact car. During the collision: the
- truck exerts the same amount of force on the car as the car exerts on the truck.
- neither exerts a force on the other, the car gets smashed simply because it gets in the way of the truck.
- the truck exerts a force on the care but the car does not exert a force on the truck.
- the truck exerts a greater amount of force on the car than the car exerts on the truck.
- the car exerts a greater amount of force on the truck than the truck exerts on the car.
2. Two metal balls are the same size, but one weighs twice as much as the other. The balls are dropped from the roof of a single-story building at the same instant of time. The time it takes the balls to reach the ground below will be:
- about half as long for the lighter ball.
- about the same time for both balls.
- considerably less for the heavier ball, but not necessarily half as long.
- about half as long for the heavier ball.
- considerably less for the lighter ball, but not necessarily half as long.
