Parametric equation

  1. Nov 12, 2007 #1
    1. The problem statement, all variables and given/known data

    At time t, a projectile launched with angle of elevation a and initial velocity Vo has position x(t)=(Vocosa)t and y(t)=(Vosina)t-0.5gt^2, where g is the accerleatio due to gravity.

    3. The attempt at a solution

    (a) A football player kicks a bal at an angle of 36degrees above the ground with an initial velocity of 60 feet per second. Write the parametric eqaions for the position of the gootbal at time t seconds. g=32 ft/sec^2.

    => Solution: x(t)=(60cos36)t

    (b) Graph the path that the football follows.
    => I did come up with the equations but I have no idea how to draw a graph out of them.

    then shouldn't t=x/(60cos36)

    sub that into your equation with y
