Amy is driving her 2400 kg car down the road, and the car produces a force of 7200 N. How fast is Amy accelerating?

The acceleration of Amy's car is 3 m/s²

Explanation:

Given;

mass of Amy's car, m = 2400 kg

force of the car, F = 7200 N

According to Newton's second law of motion, the force of the car is given as;

F = ma

where;

a is the acceleration of the car

Substitute the given parameters and solve for acceleration;

a = F / m

a = (7200) / (2400)

a = 3 m/s²

Therefore, the acceleration of Amy's car is 3 m/s²

because growing process had stoped after 4-5 year

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
