Answer 2

Answer:

A car moving aling a straight highway with speed of 126 km h^(-1) is brought to a stop within a distance of 200 m. What is the retardation of the car (assumed uniform ) ans how doest it take fro the car to stop ? Here, u=126h-1 = ( 126 xx1000 )/( 60 xx 60)1 ms^(-1) =35 ms^(-1) , v=0.
