Question

a car is moving with a velocity of 72km/h with uniform acceleration 2MLS if gov apply brakes suddenly what is the distance traveled in 10 sec​

Answer 1

Answer:

V=0

U=72km\hr, 72×5/18 = 20 m/s

S=50m

Apply equation

V^2=U^2+2as

0 = 20^2 +2×50×a

0 = 400 + 100×a

-400 = 100a

a = -400/100

a = -4m/s^2
