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.

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,

image001

= 0.1 x 60 x 120 = 720 m
