1.	A car is moving with a velocity of 2m/s. When the driver applied break, it come to rest by 4sec. Calculate the retardation of the car.
Answer» As we KNOW,retardation is opposite of acceleration.So,final velocity= 0m/sinitial velocity=2m/sTotal time= (final - Initial) time=( 4 - 0)s = 4sRetardation of the car= (final - initial) velocity/Total time = (0-2)m/s / 4s=-2/4 m/s^2= -1/2 m/s^2Hence the retardation of the car is -1/2m/s^2Explanation:HOPE u LIKE it!☺️☺️
