A golf ball is hit with an initial angle of 30.5° with respect to the horizontal and an initial velocity of 81.9 mph. It lands a distance of 86.8 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?

Write an ideal (zero resistance) equation for vertical height vs time and compute the time and location where the ball lands (Z = 0). Compare that with the actual distance where it lands.

Is that ball speed really miles per hour or meters per second? If it is mph, convert the speed to meters per second before doing the problem.

86.8 meters is not a very long golf shot. If the ball is only hit at 30.5 degrees to horizontal, the wrong golf club choice was probably made
