Question

The brakes on a truck fail as it approaches a car stopped at a red light. Use Newton’s first and second law of motion to explain what will happen when the truck collided with the car.

Answer 1

The car will roll forward about the same speed that the truck collideed with it, and the truck will slow down greatly but still move a little.

Answer 2

newtons first law states that a object in motion will stay in motion unless acted on by an outside force and an object at rest will stay at rest for the same reason. the force of a moving object is equal to its mass times its acceleration.
