Projectile Motion (No initial velocity)

  1. Sep 13, 2008 #1
    1. The problem statement, all variables and given/known data
    A salmon starts 2.00 m from a waterfall that is 0.55 m tall and jumps at an angle of 32.0. What must be the salmon's minimum initial speed to reach the waterfall.


    2. Relevant equations
    [tex]\Delta[/tex]y=visin[tex]\Theta[/tex][tex]\Delta[/tex]t+1/2g[tex]\Delta[/tex]t2

    3. The attempt at a solution
    I have tried all the related formulas for projectile motion, and I felt like I got somewhere a few times. But the results aren't really checking with a graphing calculator.

    You need to show your work in order to get help here.

    What have you tried so far? And what exactly does the graphing calculator not agree with?
