          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
