t = 2 * d / (f + i)
d = 290m
f = 0 (car stopped!)
t = 10 s
Theres a car accident.
Skid marks are as long as 290.0 m were left by the car as it decelerated to a complete stop.
The police report cited the speed of the car before braking to be "in excess of 161 km/h".
Suppose it took 10.0 seconds for the car to stop.
Estimate the speed of the car before the brakes were applied.
(answer should read "speed in excess of...")
I know the equation, but im having a hard time naming the variables.
The equation is
t = (2*distance)/(final velocity + Initial velocity)
