    Calculating Speed and Time of Nolan Ryan's Baseball Orbit on the Moon

    Suppose that Nolan Ryan stands on the surface of the moon and throws a baseball horizontally. If the baseball has a high enough speed and does not strike any mountain, it can orbit around the moon and, after completing the orbit, strike Nolan from behind. The mass of the moon is mm =...

    Calculating Max. Distance of Block on Turntable Rotating at 33 1/3 rev/min

    The coefficient of friction between a certain brass block and a large revolving turntable is µ = 0.17. How far from the axis of rotation can the block be placed before it slides off the turntable if it is rotating at 33 1/3 rev/min? i was wondering was this the equation to solve this...
