Question

A bus starting from rest moves with a uniform acceleration of 0.1 meters per second for 2 minutes. find 1 the speed aquired 2 the distance travelled

Answer 1

u =0
a = 0.1 m/s²
t =2 min = 120 sec

as,v = u+at
        =0 +0.1×120
        = 12 m/s

and,v² - u² = 2as
⇒(12)² - 0 = 2×0.1×s
⇒0.2s = 144
⇒s = 144/0.2
      =720 m
