A golf ball is hit with an initial angle of 54.7o with respect to the horizontal and an initial velocity of 85.1 mph. It lands a distance of 104.3 m away from where it was hit. By how much did the effects of wind resistance, spin, and so forth reduce the range of the golf ball from the ideal value?

  • Physics - ,

    The ideal range is
    (Vo^2/g)*sin(2*54.7)

    Subtract 104.3 m from that for the answer.

    You will have to convert 104.3 mph to m/s before applying the formula.

    That is an extremely slow speed for a golf ball. A reasonably healthy person can throw a golf ball at that speed.

  • Physics (correction) - ,

    I meant 85.1 mph for the speed that must be cnverted to m/s
