Question

A golfer gives a ball a maximum initial speed of 23.5 m/s.Neglect air resistance)          (a) Whatis the longest possible hole in one for this golfer? Neglect anydistance the ball might roll on the green, and assume that the teeand the green are at the same level.   (Meters)?             (b)What is the minimum speed of the ball during the hole in oneshot?        (M/S)?

Explanation / Answer

initial speed v = 23.5 m / s (a). Longest possible hole D = v ^ 2 / g                                             = 56.35 m (b). Minimum speed = v cos 45
