I figured it out! Thank you so much!

I am still confused. "The current is given?" maybe I am just fundamentally misinterpreting the diagram. Does it say "1A" or "IA." and either way, what does it mean?

so if I use V=IR how would I calculate I? I= V/R. but what do I plug in as the resistance? I am so bad at physics :(

i'm still confused... are you saying 120v * 1 amp? Sorry, I am really bad at electricity, but don't the turns mean anything?

so i would first need to find the time in the air. This can be determined by vertical motion, but would it be at the same 135m/s even though it is at a 60 degree angel, or would i need to use vectors/trig in order to find the velocity at 60 degrees?

A projectile is fired straight upward at 135 m/s. How fast is it moving at the instant it reaches the top of its trajectory? My answer: 0 m/s Suppose instead it were fired upward at 35°. What would be its speed at the top of its trajectory? m/s I do not know how to approach...
