일반물리학 1 — Motion in Two and Three Dimensions: Problem 24

24 In the 1991 World Track and Field Championships in Tokyo, Mike Powell jumped 8.95 m, breaking by a full 5 cm the 23-year long-jump record set by Bob Beamon. Assume that Powell’s speed on takeoff was 9.5 m/s (about equal to that of a sprinter) and that \(g = 9.80 \text{ m/s}^2\) in Tokyo. How much less was Powell’s range than the maximum possible range for a particle launched at the same speed?
