(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In each case, draw a set of graphs for the vertical and horizontal components of motion. Also draw a motion map of the vertical and horizontal components of motion.

A projectile is launched with a speed of 30 m/s at an angle of 30 degrees. At a point which is ½ the way down from it’s highest point, what is the actual velocity vector (answer includes both magnitude and direction).

2. Relevant equations

Vox = Vo*cos(theta)

Voy = Vo*sin(theta)

a = Voy - gt

x = Xo + Vot + 1/2(at)^2

v = Vo + at

A + B = Midpoint

3. The attempt at a solution

I drew a vector diagram that helped me find Vox and Voy using the equations listed above. I got Vox = 25.9808 m/s and Voy = 15 m/s.

Then, I got the maximum height at 1.23718 seconds using the Voy equation and then since the half way point is essentially the midpoint of the total time it takes for the projectile to reach the ground, I took the midpoint of the final time and the maximum height time and got 1.85577 seconds.

I'm lost on how to go from here or what I'm to do... Please help if possible?
