t is the time for Tina to catch David
1/2 a t^2 = v t
1.45 t^2 = 24 t
1.45 t^2 - 24 t = 0
t = 24/1.45
distance = 24 * 24/1.45
speed = accel * t = 2.9 * 24/1.45
David is driving a steady 24.0m/s when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.90m/s2 at the instant when David passes.
How far does Tina drive before passing David?
What is her speed as she passes him?
