Question

Physicist Phil was driving aroud a flat curve at 9.1m/sec. Being a physicist, he knew that if he went around the curve at the maximum speed which would allow him to stay on the road, then the static force (F (little a)) would equal the centripital force (F (little c)). If (F (little a)) = 5.209m m/sec^2, (F (little c)) = mv^2/r m/sec^2, Phil's car has a mass, m, of 800 kg, the radius, r, of the curve is 75m, and v is the speed of the car in m/sec, how much faster, in m/sec, could Phil go and still stay on the road? Give your answer rounded to four significant digits.

Answer 1

What's the question? You have all the formulas, you have all the values. What more do you need?
