Question

A bus starting from rest moves with a uniform acceleration of 0.1m/s2 for 2 minutes. Find (a)the speed acquired (b) the distance travelled

Answer 1

Answer:

a) 12m/s b) 720m

Explanation:

Use SUVAT:

a) u=0 a= 0.1  t= 2mins = 120 seconds v=?

v=u+at

v= 0 +(0.1*120)

v=12m/s

b) s=? u=0 a=0.1 t=120

s=ut+1/2at^2

s=0*120+1/2*0.1*120^2

s=720m
