Question

Problem #2 An 800 kg car is traveling on a circle of radius 60 meters on a surface that has a coefficient of static friction between the car's tires and the road of 0.20. The banking angle is 10 degrees. A free body diagram of the car is shown bellow. Ffriction (a) Find the car's apparent weight. (Hint: Car'a apparent weight - INI) (b) Find the car's maximun velocity at which it will not lide and move in a circle

Answer 1

static friction, Ms = 0.2 Solution 800kg Given that, mass, ma augle, O=10 radins, p=60m mun or, mun I fx= = Nsina tlus Neos o Ify = 0 = Neoso - MN sing-mg from this two equation, we get 'ng (sing tills Caso) = 15.145 mls COBO -lls sino Now, the apparent weight, N = mg coso - Mssine =8251.IN.
