A crossbow is positioned at the top of a castle wall overlooking a flat and level field below. The crossbow fires bolts at an initial speed of 100 m/s. First, the crossbow aims at an angle of 25 above horizontal, and the first shot lands 800 m away from the base of the castle wall. Next, it aims horizontally, and the second shot is fired. 2. What are the horizontal and vertical components of the initial velocity (Vox and voy) of the first shot? (Hint: draw a triangle) 3. What is the air time (t) of the first shot? 4. What is the height (s,) of the castle wall above the ground below? 5. Calculate the air time (t) and range (s,) of the second shot.
