A typical automobile under hard braking loses speed at a rate of a(7.0 m/s²). A typical reaction time to engage the brakes is tᵣ (0.50 s). If a car is initially traveling at a velocity v₀, what is the stopping distance for the automobile?
(A) Draw a diagram to help conceptualize the problem and label it with variables. Identify (and write down) what is known and what is unknown from the problem.
