d = Vo*t + (V^2-Vo^2)/2a
d = 20*0.5 + (0-20^2)/-10 = 50 m.
Note: Vo*t is the distance traveled
during the reaction time.
The 2nd Eq was derived from
V^2 = Vo^2 + 2a*d. Solve for d.
You're driving down the highway at 20m/s when you see a snowman you don't want to crush 35 m in front of you. Your reaction time before stepping on the brakes is 0.5s, and acceleration created by your brakes is 10 m/s^2 what was the distance travelled before coming to a stop?
I would appreciate it if you show me the equation you're going to use.
