Question

A car speeds up from rest to 40 m/s in 5 s. Find the car speed at 2 s and overall

Answer 1

Answer:

I would have to say that i feel that after 2 seconds it would be 8 m/s and the overall distance would be 200 m but don't quote me on it

Explanation:

Answer 2

If a car goes from rest to 40 m/s in 5 seconds it means the acceleration is 8 m/s/s. After 2 seconds the speed is 16 m/s and the overall distance = 1/2 x 40 x 5 = 100m
