Question

A bus starting from rest moves with a uniform acceleration of 0.1 m/s square for 2 min.Find

A.the speed acquired

B.distance travelled


Solution

Initial velocity, u=0 (Rest) 

acceleration,a=0.1m/s²

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

The speed acquired, 
  v=u+at
     0+(0.1*120s)
      =12m/s

Distance, s=ut+¹/² at²
                   
=0+¹/²*0.1*120*120
=720m
