I am working on finding the inital velocity of a class II projectile and am having trouble determining the right amount of sig figs. The taken measurements of the initial position of x goes to 4 sig figs, as well as the final position for y. With that being said, I am trying to find the initial velocity of x and y separately through trionometry. For example, if I have an equation for the initial velocity of x with an angle of 40, then Vox=Vocos40 My question is, since the measured value for my angle is two significant figures, is my answer Vox=.76Vo also in two sig figs because it goes by the two significant figures from my measured angle, or should I go to four significant figures to match my measured values for x and y?
I need to solve v(sub y)=v(sub 0)sin θ(sub 0)-gt to find the time that it takes the projectile to reach maximum height (so I believe I'm solving for t?). I have previously found v(sub 0y) in part (a), but I'm unsure what v(sub 0) and v(sub y) are. How do I find those variables?

A parent at a Little League game returns a foul ball by throwing it back onto the field. When the parent throws the ball back, she is standing and ends up releasing the ball from a point that is 2.50m above the ground. Your best guess is that she threw the ball upward at an angle of 60o with respect to the ground and it landed 13m away from her. What was the height of the ball's apex (as measured from the ground)?
