A bus decreases its speed from 80 km//h ...

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

Text Solution

Verified by Experts

Initial speed of the bus, `u=80km//h=80xx(5)/(18)=22.22m//s`
Final spedd of the bus, `v=62 km//h= 60xx(5)/(18)=16.66 m//s`
Time take to decrease the speed, t = 5s
Acceleration, a =`(v-u)/(t)=(16.66-22.22)/(5)=-1.112m//s^(2)`
