A driver is traveling 18.4 m/s when she sees a red light ahead. Her car is capable of decelerating at a rate of 3.65 m/s^2 . How far from the beginning of the intersection will she be?

Answer»

46.38 mExplanation:INITIAL VELOCITY, u=18.4m/sFinal velocity, v=0 m/sAcceleration, a=-3.65m/s²Using the third equation of MOTION,v²-u²=2aSS=(v²-u²)/2a = -(18.4²)÷(2×-3.65) = 46.38 m
