Question

A bus running at a speed of 18 km/h is stopped in 2.5seconds by applying brakes. Calculate the retardation produced

Answer 1

Heya user
Here is your answer !!

Speed of the bus in km/hr = 18 km/hr
So , speed of the bus in m/s = 5 m/s .

Time taken to stop the bus = 2.5 s .

Hence , retardation produced is = ( 5 m/s ) / 2.5 s = 2 m/s² {Answer}

NOTE :
1 km/hr = 5/18 m/s
1 m/s = 18/5 km/hr .

Hope it helps !!
