A car is moving 60 km/h when the driver sees a signal light 40 m ahead turn red. The car can slow with an acceleration at the -.5g, where g is 9.8 m/s^2. What was her stopping distance? Assume zero reaction time. You should convert 60 km/h to m/s.

Answer:

28.34m

Step-by-step explanation:

initial velocity = 50/3 m/s (U)

final velocity= 0 (V)

acceleration= -4.9 m/s^2 (A)

S= V^2-U^2/2A

S= 28.34m
