A car moving with a speed of 180km/hr was brought unformily to rest by the application of brakes in 20s. How far did the car travel after the brakes were applied?

Question

aditya shankar · Answer

apply formula u=180km/hr=180*5/18=50m/s t=20s v=50-a*20 since final velocity is zero so, 0=50-20a ,a=2.5m/s s=ut+.5gt^2 s=50*20-0.5*2.5*20*20 =1000-500 =500m
