Question

a driver of a car travelling at 36 km per hour applies the brakes and accelerates uniformly in the opposite direction the car stops in 5 second another driver going at 5 kilometre per hour in another ka applies brakes slowly and stops in 10 second which of the two castor oil for the after the brakes are applied​

Answer 1

Answer:

first,let us convert both speed in m/s.

conversion from km/h to m/s

1km=1000m

1hour=60 minutes=3600s

1km/h = 1000m/3600s

1km/h=5/18m/s

car 1

initial velocity=52m/h

52*5/18m/s

130/18m/s

=14.44m/s

initial velocity=0m/s

time = 5 second

now,

car 2

initial velocity=3km/h

= 3*5/18m/s

5/6 m/s

0.833m/s

initial velocity=0 m/s

time = 10 second
