Question

1. A bus starting from rest moves
with a uniform acceleration of
0.1 m s-2 for 2 minutes. Find (a)
the speed acquired, (b) the
distance travelled.​

Answer 1

Answer:

(a)speed acquired=120m/s

(b)distance travelled=7200m/7.2km

Explanation:

Here we have initial velocity(u)=0

acceleration (a)=0.1ms-2

time(t)=2 min=120s

a) the speed acquired:

we know,v=u+at

v=0+0.1m/s2×120s

v=120m/s

THE SPEED ACQUIRED=120m/s

b)distance travelled:

we know...s=ut+1/2at2

s=0×120s+1/2×0.1m/s2×(120s)2

s=1/2×14400=7200m or 7.2km

DISTANCE TRVELLED=7200m/7.2km
