Problema Solution
the polynomial 3.675v+0.096v^2 is used to estimate the stopping distance in feet for a car whose speed is v miles per hour on flat dry pavement. What is the stopping distance for a car traveling at 70 miles per hour?
Answer provided by our tutors
the stopping distance is a function of the speed v:
d(v) = 3.675v+0.096v^2
we want to find the stopping distance for v = 70 mph.
plug v = 70 mph into d(v) = 3.675v+0.096v^2
d(70) = 3.675*70+0.096*70^2
d(70) = 727.65 mi
