Question

Bus of starting from rest moves with uniform acceleration of 0.1 ms for 2 minutes. Find (a) the speed acquired (b) the distance travelled.

Answer 1

Answer:

(a)=0.2 (b)=

Explanation:

u=0m/s

a=0.1m/s^2

time=2min=120sec

by equation 1st

v=u+at

v=0+0.1*120

v=12m/s

by equation 3rd

v^2-u^2=2as

12^2-0=2*0.1*s

144=0.2*s

144/0.2=s

s=720meter
