Question

A bus accelerates uniformly from 54 km/h to 72 km/h in 10 seconds Calculate

       (i)  acceleration in m/s2

       (ii)  distance covered by the bus in metres during this interval.​

Answer 1

Answer:

acceleration =0.1 m/s2 and distance = 35 m

Explanation:

v = u + at

and S = ut + 1/2 at^2

Answer 2

accn=v-u

accn=72-54

accn=18

in m/s

18*5/18m/s

=5m/s
