Question 240732: The stopping distance of (s) of a car varies directly as the square of it's speed (v). If a car traveling at 30 mph requires 63 ft to stop, find the stopping distance for a car traveling at 50 mph.
You can put this solution on YOUR website! The stopping distance of (s) of a car varies directly as the square of it's speed (v).
If a car traveling at 30 mph requires 63 ft to stop,
:
find the stopping distance for a car traveling at 50 mph.
s = stopping dist at 50 mph
: +
: +
cross multiply
900s = 63*2500
s =
s = 175 ft
