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=VoT
Y equation (Delta)y=Vyot+1/2Ayt^2
Solve for time then you can plug that in and get Vyo
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...
Homework Statement
I need to know the units of the slope. What the slope should be. And the percent error.
