In a performance test, each of two cars takes 9.0 s to accelerate from rest to 28 m/s. car a has a mass of 1379 kg, and car b has a mass of 1902 kg. find the net average force that acts on (a) car a and (b) car b during the test.

Explanation:

It is given that,

Mass of car A,

Mass of car B,

In a performance test, each of two cars takes 9.0 s to accelerate from rest to 28 m/s. Their acceleration is given by :

a = 3.12 m/s²

(a) The net force of car A,

(b) The net force of car B,

Hence, this is the required solution.
