Projectile Motion: canon shot

  1. Oct 29, 2016 #1
    1. The problem statement, all variables and given/known data
    The Great Projecto is fired from a cannon at a velocity of 29.8 m/s at an angle of 50.4 degrees. He lands in a net which is 2.0 m above his starting elevation. What is his velocity when he hits the net? How do I find it with no starting elevation?
    vx1: 36.02 m/s vy1: 19.0 m/s
    vy2=?
    vx2: 36.02 m/s a= -9.8/ms
    a=0


    2. Relevant equations



    3. The attempt at a solution

    Hi gungo, Welcome to Physics Forums.

    You need to make an attempt at solution in the indicated area of the template. Even if you can't solve the problem completely or correctly, you should at least be able to write down relevant equations for this type of problem.

    If you look carefully at the problem statement you will see that he lands 2.0 meters above his starting elevation. So pick any starting elevation you like.

    The magnitude of one component of velocity cannot exceed the magnitude of the overall velocity.
