Homework Help: Trajectory tennis problem help

  1. Mar 2, 2014 #1
    1. The problem statement, all variables and given/known data
    Consider tennis net which is 2 ft high at its center point; the service line is 20 ft from the net, and the baseline is 30 ft from the net. You have a bullet-like service that travels in a straight line, just clearing the net before hitting the service line.
    a) What angle does the trajectory of this serve make with the horizontal?
    b) At what height above the ground is the ball struck with the racket?


    2. Relevant equations

    how do i find a tracetory angle?


    3. The attempt at a solution

    v^2=vo^2 +2-g(y-yo) vf=0m/s vi=? y=0 yo=2ft g=9.8?
