A bus starts from rest and moves with a uniform acceleration of 1ms−2. A boy 10m behind the bus at the start runs at a constant speed and catches the bus in 10s. Speed of the boy is :
Solution 2
Distance travelled
by bus in 10s⇒12×1×102=50m
D = Distance boy has to cover =10+50=60m
Speed
of boy =DT=6010=6 m/s
