Question

A bus starting from rest moves with a uniform acceleration of 0.1 m s-2 for 2 minutes. Find [a] the speed required, [b] the distance travelled.

Answer 1

Answer:

a)

acceleration =0.1ms-2

t=2min(2×60=120)

u=0m/s

(v=u+at)

v=0+0.1(120)

v=.1(120)

v=12m/s

B)

s=ut+1/2at-2

s=0(120)+1/2(0.1)(120)(120)

s=.1×60×120

s=6×120=720m

s=720m
