F = ma for $100 The magnitude of the force that a car exerts on a brick wall (after slamming into it) is 3000 Newtons. What is the magnitude of the force that the brick wall exerts on the car and which of Newton’s Laws does this support?

F = ma for $200 Draw a position vs. time graph that shows a net force of zero. Remember, the slope of a position vs. time graph is the object’s velocity.
