### Q.:- A bus starting from rest moves with a uniform acceleration of 0.1 ms^{-2} for 2 minutes. Find

### (a) the speed acquired,

### (b) the distance travelled.

*Answer:-*

Here,** **acceleration a = 0.1 ms^{-2}

Time *t* = 2min = 2 x 60 = 120s

Initial speed *u* = 0

(a) From Ist equation of motion, speed acquired, *v* = *u* + at

= 0 + 0.1 x 120

** **= 12 ms^{-2}

(b) From IInd equation of motion,

Distance travelled,

= 0.1 x 60 x 120 = 720 m
