Question

a bus decreases its speed from 60km/hr to 40 km/hr in 5s find the acceleration of the bus

Answer 1

hey dear
here is your answer

given data :

initial velocity (u) = 60 km/hr or 16.67 m/s

final velocity (v) = 40 km/hr or 11.12 m/s

time (t) = 5 seconds

to find : acceleration

here we go

solution :

by using first equation of motion

v = u-at ( we are using negative sign before acceleration because body is retarding)

11.12 = 16.67-5a

5a = 5.55

a = 1.11 m/s²

hope it helps :)
