Acar manufacturer wants to change its car’s design to increase the car’s acceleration. which changes should the engineers consider making to the design? increase the force that the engine provides decrease the force that the engine provides increase the mass of the car decrease the mass of the car increase the top velocity the car can travel decrease the top velocity the car can travel

increase the force that the engine provides

decrease the mass of the car

Explanation:

According to Newton's second law, the force exerted by the engine is equal to the product between the car's mass and its acceleration:

We can re-arrange the formula as follows:

from which we see that:

- the acceleration is directly proportional to the force exerted by the engine, F, therefore the engineer could increase the force that the engine provides in order to increase acceleration

- the acceleration is inversely proportional to the mass of the car, m, so the engineer could decrease the mass of the car in order to increase acceleration
