Question

A bus is moving at a speed of 72km/h. on applying brake it come to rest in 5 sec find the acceleration distance covered by the bus.​

Answer 1

Answer:

a = -4 m/s²

Explanation:

72 kmph = 20 m/s

v  = u + at

0 = 20 + 5a

a = -4 m/s²

Answer 2

Acceleration=V/T=Velocity/Time
First we have to convert km/h to m/s.
72km/h
=Km/h
=1000m/3600sec
=1000x72/3600
=72000/3600
=20m/s
We know that,Acceleration=Velocity/Time
So,
Acceleration=20/5 m/s^2
Acceleration=4 m/s^2

Answer=4 m/s^2
