Answer 1

I hope this will clear your doubts related to this question.

Answer 2

Heya !!!

This is your answer....

Given : ---
Mass, m = 2000 kg.
Distance = 40 m. and
time = 6 sec.

We know that work done = 1/2×mv^2

V = s/t
= 40/6 = 20/3 m/s.

Now.....

1/2 × 2000 × 20/3 × 20/3
= 1000 × 400/9
= 400000/9
= 44444.44 N.

Hence the work done by the car is 44444.44 Newton...

Hope it helps
