Greetings once again,

I'm sitting here doing my physics lab and these questions confuse me. I think I know how to approach and solve it but i'm not really sure. I really need some clarification/help on. So please help me.

1) Use the length of string (2.405m) and the distance along the floor (1.7157m) to compute theta. (The 0 thingy) Determine your height using theta and f. No idea on how to even start this one.

2) Use the angle (43°) and the distance along the floor (1.7157m).

For this one I think I should use Tan (43°) = h divided by 1.7157m ? H=1.6m?

3) Use the angle (43°) and the length of the string (2.405m).

I think you use Sin (43°) = h divided by 2.405m? H = 1.64m?

4) Use the pythagorean theorem.

I think you have to use the 3 questions above to do this.

Please help!

Thank you in advance.
