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 [tex]force=mass\times acceleration [/tex]
[tex]Force=mass \times 0=0 N[/tex]
