    Circular Motion -

    1. (a) Find the proper banking angle for cars moving at 50 mi/h to go around
    a curve 1000 ft in radius.
    (b) If the curve were not banked, what coefficient of friction would be
    required between the tires and the road?

    2. A string 0.5 m long is used to whirl a 1 kg stone in a vertical circle a
    uniform velocity of 5 m/s. What is the tension in the string
    (a) when the stone is at the top of the circle and
    (b) when the stone is at the bottom of the circle?

    (1) (a) Angle of banking = Theta = arctan(v^2 /rg)

    50 mi/h = 22.352 m/s, 1000 ft = 304.8 m

    Theta = arctan [22.352^2 /(304.8 * 9.8)] = ...
