Question

it takes less force to stop a car than a semi - truck. (both are going at the same speed)
newtons 2nd law
newtons 1st law
newtons 3rd law

Explanation:

Newton's 2nd Law states \( F = ma \). Since the car has less mass (\( m \)) than the semi - truck and they have the same acceleration (to stop), by \( F = ma \), less force (\( F \)) is needed for the car.

Answer:

Newton's 2nd Law
