Question

A bus decreases its speed from
80 km h to 60 km hl in 5 s.
Find the acceleration of the bus..

Answer 1

acceleration = Change in velocity / time taken

= (( 60 - 80 ) * 1000/3600 )/5

= -1.11 m/sec2 (deceleration)

Answer 2

given:-

Initial velocity ,u = 80km/h

Final velocity ,v = 60km/h

Time taken ,t = 5 s

Hence, the acceleration of the bus is approximately 1.12 m/s²
