A cannon ball is fired from a catapult at 13.5 m/s at 24 degrees above the horizontal. a. How long is it in the air? b. What is the horizontal component of the velocity? c. How far from the catapult does the ball land? I used a program on my calculator that we are allowed to use and got the X Magnitude to be 12.3 and the Y Mag. to be 5.5..with that i filled in this chart: vX 12.3 dX t vfY 5.5 voY dY t aY -9.8 i need a third component in the Y column, then i can figure out how to do the rest. How would I go about finding it?
