일반물리학 1 — Motion in Two and Three Dimensions: Problem 38

38 A golf ball is struck at ground level. The speed of the golf ball as a function of the time is shown in Fig. 4-27, where t = 0 at the instant the ball is struck. The scaling on the vertical axis is set by \( v_a = 19 \text{ m/s} \) and \( v_b = 31 \text{ m/s} \). (a) How far does the golf ball travel horizontally before returning to ground level? (b) What is the maximum height above ground level attained by the ball?
