Question

Some race cars are equipped with parachutes to help bring the car to a stop. Which most likely causes the change in the velocity of the race car?

A.a balanced force exerted by the parachute
B.an increase in the force exerted by the car
C.a net force of zero between the car and parachute
D.an unbalanced force between the car and parachute

Answer 1

The change in velocity of a race car equipped with a parachute is most likely caused by an unbalanced force between the car and parachute.

Step-by-step explanation:

The change in velocity of a race car equipped with a parachute is most likely caused by D. an unbalanced force between the car and parachute. When the parachute is deployed, it creates air resistance or drag force. This drag force acts in the opposite direction to the car's motion, creating an unbalanced force and causing the car to slow down and ultimately come to a stop.
