Question

A bus decreases its speed from
80 km h to 60 kmh in 5 S.
Find the acceleration of the bus​

Answer 1

Answer:

a= -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

Answer 2

answer=. -27.7m/s^2

Explanation:

initial velocity is given 80 km h

final velocity is given 60km h

as we know a=v-u/t
