If a car at rest, accelerates uniformly ...

If a car at rest, accelerates uniformly to a speed of `144 km//h` in `20s`, it covers a distance of

A

20m

B

400m

C

1440m

D

2980m

Text Solution

Verified by Experts

The correct Answer is:
B

`v=144xx(5)/(18)=40 m//sec t=20` sec
`s=((u+v)/(2))t=((0+40)/(2))20=400m`
