Question

Find the force it would take to accelerate an 800-kg car at a rate of 5m/s2.

Answer 1

Answer:

4000 N

Explanation:

According to Newton's second law, a resultant force is equal to mass times acceleration. i.e

$F_{net} = ma = 800 kg * 5 m/s^{2} = 4000 N$

So assuming that there is no other force that is acting on this car, a force of 4000 N would cause the acceleration mentioned in the question.

Answer 2

Force= mass•acceleration

Force=800•5

Force=4000 N
