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

Text Solution

Verified by Experts

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