SOLUTION: The force required to keep a 2000lb car going 30mph from skidding on a curve, where r is the radius of the curve in feet, is given by the following formula F(r)= 225,000/r A)

Question 1085678: The force required to keep a 2000lb car going 30mph from skidding on a curve, where r is the radius of the curve in feet, is given by the following formula
F(r)= 225,000/r
A) what radius must a curve have if a force of 450lb is needed to keep the car from skidding?
B) as the radius of the curve is lengthened, how is the force affected?
