A person in a lab wants to make a car accelerate faster. Should the person: O decrease the mass
o increase the mass
O lower the force

Decrease the mass.

Explanation:

By Newton's Second Law we know that net force exerted on a given system equals the rate of change of linear momentum () in time.

(Eq. 1)

When mass of the system has a constant mass, this net force () is reduced to its mass () multiplied by acceleration ():

(Eq. 2)

If we keep net force exerted on system constant, then a decrease on mass is compensated by an increase in acceleration. Hence, correct answer is: Decrease the mass.
