If a sporsts car at rest accelerates uniformaly to a speed of `144 km h^(-1)` in 5 s, it vovers a distance of ___________m

Options

A. 100
B. 140
C. 60
D. 80

Explanation

`u=0`
`v=144km h^(-1)=144xx(5)/(18)m s^(-1)=40 m s^(-1)`
`t=5s`
`a=(v-u)/(t)=(40)/(5)=8 m s^(-2)`
`s=(1)/(2)xx8xx(5)^(2)=100m`
