Question

a car is parked in a parking lot. if the car exerts a 75 n downward force on the ground, what reaction force will the ground exert on the car?

Explanation:

Step1: Apply Newton's third law

Newton's third law states that for every action, there is an equal and opposite reaction.

Step2: Determine the reaction force

The car exerts a \(75\) N downward force (action) on the ground. So, the ground will exert an equal (\(75\) N) and opposite (upward) reaction force on the car.

Answer:

\(75\) N upward
