A bus starting from rest moves with a uniform acceleration of `0.2ms^(-2)` for 3 minutes. Find the speed and distance travelled.

Text Solution

Verified by Experts

Initial velocity 'u' = 0
Acceleration `'a'=0.2ms^(-2)`
Time (t) = 3 minutes = 180 seconds.
Speed of a bus, `v=u+at=0+0.2xx180`
`=36m//s`
Displacement `s=ut+(1)/(2)at^(2)`
`=0xx180+(1)/(2)xx0.2xx(180)^(2)=0+(1)/(2)xx0.2xx32400`
`=3240m=3.24km`
