    VERY DIFFICULT 2-D Motion Problems

    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

    Finding Tension when Mass Accelerates

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

    Help With Graphs Homework: Units of Slope, Slope Value, & Percent Error

    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...

    Which spot on earth would have the fewest # of satellite's visible?

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

    Tension of string between two blocks

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