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.

(a) Given, Initial velocity (u) = 0 Acceleration (a) = 0.1 ms -2 Time = 2 minutes Convert min into sec 1 min = 60 sec So, 2 min = 2 x 60 sec = 120 s v = u + at Substituting we get, v = 0 + (0.1 x 120) = 12 Hence, speed acquired = 12 ms -1 (b) According to the third equation of motion, 2as = v 2 - u 2 or s = Since a = 0.1 ms -2 v = 12 ms -1 u = 0 t = 120 s Substituting we get, s = = 720 m. Hence, the total distance travelled is 720 m
