Question

A bus starting from rest moves with a uniform acceleration of 0.1ms^-2 for 2minutes. Find the speed acquired and the distance travelled

Answer 1

If it's starting from rest then ,
Initial velocity=0
Acceleration=0.1m/s²
Time= 120 sec
As s=ut+½at²
Distance is 0x120+½x 0.1x 120 x 120= 720m
Speed= distance by time
S=720/120=6m/s
I hope it helps you....
