Question

A bus decreases its speed form 80kmh-1to 60kmh-1 in 5s find the acceleration of the bus

Answer 1

here is your answer

given :

initial velocity (u) = 80 km/hr = 80×(5/18) = 22.23 m/s

final velocity (v) = 60 km/hr = 60×(5/18) = 16.67 m/s

time taken (t) = 5 seconds

to find : acceleration

solution :

acceleration = change in velocity / time taken

acceleration = (v-u)/t

acceleration = (16.67-22.23)/5

acceleration = -1.112 m/s^2

so, the acceleration will be -1.112 m/s^2.

Answer 2

$\huge\underline\mathfrak\purple{Solution}$

Initial velocity = 80 km/hr = 22.22m/s

Final velocity = 60km/hr = 16.66m/s

Time = 5s

Acceleration = [16.66 - 22.22]/5

The acceleration of bus is -1.11 m s-2
