    Finding Initial Velocity and Angle in 2D Kinematics Problem

    does Tan theta = 9.8/16 ? am i on the right track?

    Finding Initial Velocity and Angle in 2D Kinematics Problem

    is it an easy Trigonometric solution? I am in Trig/precalc algebra in one class and we just started the Trig half, so maybe I am not familiar with a function to equate Sin/Cos?

    Finding Initial Velocity and Angle in 2D Kinematics Problem

    OK, maybe 16/cos theta = 9.8/sin theta? im so lost...

    Finding Initial Velocity and Angle in 2D Kinematics Problem

    wait, i have 16 = initial velocity * cos theta and 9.8 = initial velocity * sin theta (or is it 4.9/2 = initial Velocity * sin theta ?) (i think) now what?

    Finding Initial Velocity and Angle in 2D Kinematics Problem

    so i have: 32=(initial velocity*cos theta)*time and 0= (initial velocity*sin theta)*time - .5GT^2 right? but now what?

    Finding Initial Velocity and Angle in 2D Kinematics Problem

    it seems like you just use the dude running at 7 m/s for 2 seconds to get the total distance (18m + 14m) but i guess that's not the right way to go about it?i really wish my physics prof spoke english!

    Finding Initial Velocity and Angle in 2D Kinematics Problem

    Homework Statement A softball is hit over a third baseman's head with some speed v-sub0 at an angle theta above the horizontal. Immediately after the ball is hit, the third baseman turns around and begins to run at a constant velocity V = 7.00m/s. He catches the ball t=2.00sec later at the...

    104.5 degree triangle w/ 2 equal legs, need the 3rd leg's length

    thanks man! i think this worked, and i kind of understand why. i still don't understand why the law of cosines didnt work for me, i wonder what i screwed up...

    104.5 degree triangle w/ 2 equal legs, need the 3rd leg's length

    when i tried this i got 1.17545571, but the answer should be 1.5. C^2=(.96)^2+(.96)^2-2(.96)(.96)(-.25038)
