16s is rounded to significant figures as my instructor instructed the class on how he wanted it. I personally think I'm losing a bit by doing it but he continually stresses that we do.

Homework Statement
You are driving to the grocery store at 16 m/s. You are 130 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.50 s and that your car brakes with constant acceleration.
x1 = 0 m
v1 = 16 m/s
t1 = 0 s
x2 = ?
v2 = 16 m/s
t2 =...
