Question

A bus decreases its speed from 80km/hr to
60 km/hr in 5 sec. Find the acceleration of the
bus.​

Answer 1

Answer:

- 1.1 m/s^2

Explanation:

u= initial velocity= 80 km/h = 22.2 m/s

v= final velocity = 60 km/h = 16.7 m/s

t= time = 5 s

a= acceleration = ?

a=v-u/t

a= 16.7-22.2/5

a= -5.5/5

Therefore,

a=-1.1 m/s^2
