일반물리학 1 — Motion in Two and Three Dimensions: Problem 26

26 A stone is catapulted at time $t = 0$, with an initial velocity of magnitude $18.0 \text{ m/s}$ and at an angle of $40.0^\circ$ above the horizontal. What are the magnitudes of the (a) horizontal and (b) vertical components of its displacement from the catapult site at $t = 1.10 \text{ s}$? Repeat for the (c) horizontal and (d) vertical components at $t = 1.80 \text{ s}$, and for the (e) horizontal and (f) vertical components at $t = 5.00 \text{ s}$?
