Vyo=Vosin(theta) Vxo=Vocos(theta) Right down all your knows in a t chart. one side you x's and the other your y's ay=-9.8 delta y=7.50m Vo=36m/s There are some more x side equation is(Delta)x=volt Y equation (Delta)y=Vyot+1/2Ayt^2 Solve for time then you can plug that in and get Vyo

Thanks :)

Yeah that's right. Is this at a constant speed? Meaning no acceleration?

Yeah its suppose to be 1/t^2. I got that from Ac=(4pie^2r)/(t^2) (4pie^2r) is constant in the lab so it would be one. I had to do this since the graph that was just period v weight wasn't a straight line. And we had to find a way to get a straight line. 1/t^2=(1/t^2)*Nx+1/t^2 so it would be...

I know...

I know, pick me.

I would think the fewest would be viewed at the poles.

Start with the sum of forces in the x and y direction.

Do your some of forces for the x and y direction for both boxes. Force of tension=mass1*a

Are you doing projectile motion?

Homework Statement I need to know the units of the slope. What the slope should be. And the percent error. Pictures: http://imageups.com/files/101/456.PNG Graph 1 is function of period(1/s^2) v weight of washers(N) r=.77m mass of rubber stopper= .02kg Homework Equations f(t)=1/t^2 w=mg...
