Physics/Vectors Help?

Question

Well, my teacher assigned us homework and I've been gone for 2 weeks sick + Thanksgiving break, and I really have no idea what I'm doing. My grade right now in there is terrible, and it's dragging my GPA down a ton. It's basically a chart:

Angles | 15 | 30 | 45 | 60 | 75 | 90 | 5 | 85 |
______
Velocity | 200 | 200 | 200 | 200 | 200 | 200 | 200 | 200 |
______

V ox
_______

V oy

_______

T hang

_______

X max

_______

Y max

_______


Normally I wouldn't ask for something like this here, but my teacher is going to slaughter me if I don't get this done. I'm completley stumped and have been sitting in front of a blank piece of paper for a half an hour.

If you can't solve them, could someone at least try and explain what this is to me?

Answer 1

Some in information is missing. What is T hang for example or is it t for time? What we can do is compute velocity components.

Vox= 200 cos (15)=
Voy= 200 sin(15)=

Vox= 200 cos (30)=
Voy= 200 sin(30)=

and so on.

Answer 2

the 5 hundred and 1000 vectors are uncomplicated because of the fact they're opposite instructions. The sum is 500 down. including the three hundred varieties a triangle. 500 down, to a forty 5 degree perspective up and to the superb suited for 3 hundred. N = sqrt( 500^2 + 3 hundred^2 - 2*500*3 hundred*cos(forty 5) ) = 357.5863 Newtons locate direction employing the Sine regulation perspective = arcsin ( 3 hundred sin(forty 5) / 500) = 21.a million tiers to the superb suited of down
