What are the two strings that I should account for with accompanied tension?

Thanks for all of your help. I think I'm going to forget about the last part of the question since I got the first part correct and the assignment is due tonight. It's also not very many points so I will just figure it out later. Thanks again! Kyle

It's college physics 1. And unfortunately the problem is much more complex than I would like it to be.

Maybe if somebody could possibly work it out as far as I've gotten and could tell me if I did the first part right. It seems that I have lost my time figure aswell...:-/

So just solve for Vy? I'm not sure because that wouldn't take into account the Vox which i found above.

I would say Vy=Yo+Voy-1/2gt^2 but I'm not so sure that would solve for the velocity right before the ball hits the building. I am confused on what equation to use because none of them seem to serve a purpose for this question (number 2).

Vxfinal?

Homework Statement A baseball thrown at an angle of 65.0° above the horizontal strikes a building 18.0m away at a point 5.00m above the point from which it is thrown. Ignore air resistance. 1- find the magnitude of the initial velocity of the ball.-found 2- find the magnitude of the...

g= Vo^2sin(2a)/R ? Does that make sense for an equation finding g?

Would t=Vo/-a work from the base equation Vy=Vo+at?

t= √(2y/g)^2 is just a derivation of some sort that my professor had given us to figure time in 2d motion.

1. A boy 11.0m above the ground in a tree throws a ball for his dog, who is standing right below the tree and starts running the instant the ball is thrown. If the boy throws the ball upward at 40.0° above the horizontal, at 7.50m/s . What is velocity (m/s)? and distance (m)? 2...

I have worked through some problem solving methods that I think I need to go through to get to the next steps. I know that I need to solve for acceleration but I'm unsure as to how to do that with the equation y= yo+voyt+1/2at². Once I get the acceleration I believe I can just divide that figure...

Your spaceship lands on an unknown planet. To determine the local value of g , you ask a steel-toed crew member to kick a stone, and you find that if she kicks it at 18.0 m/s at various angles, the maximum range she can achieve is 34.8 m . What is g (m/s)? time (s)? and height (m)? I decided to...
