Question

A bus decreases its speed from 80 km/h to 50/h in 4 sec.find the acceleration of the bus

Answer 1

Hii..

here is ur answer :-

Given,

Initial velocity ( u ) = 80km/h

= 80000/ 3600 m / s

= 22.22 m/s

Final velocity ( v ) = 50km/ h

= 50000/ 3600 m/s

= 13.88 m/s

Time ( t ) = 4 seconds

Acceleration = (v -u)/ t

= (13.88- 22.22) / 4

= -8.34 / 4

= - 2.085 m / s^2

Hope it helps u!!!
