Question

If a car is traveling due westward with a constant speed of 20 m/s, what is the resultant force acting on it?

Answer 1

Answer:0

Explanation:

Given car is travelling due to westwards with a constant speed of 20 m/s

As speed is constant and it act only in one single direction therefore its velocity is also -20\hat{i}

velocity magnitude and direction is not changing therefore its change in velocity is zero and therefore acceleration is zero

and $force=mass\times acceleration$

$Force=mass \times 0=0 N$
