Rojectile equations

  1. Feb 10, 2010 #1
    1. The problem statement, all variables and given/known data

    How can you solve this? I have no idea, anything. There's a clue that it cannot be solved by the projectile equations. It can be solved using math equations. I do not know them.

    2. Relevant equations



    3. The attempt at a solution

    Re: projectile

    Apart from missing any attempt at a solution - I think you are also missing the question

    Re: projectile

    Start by writing down what you know about the motion of the stone and bird, then drawing a diagram will help

    Re: projectile

    I already have the diagram but there is only one given, the velocity of the bird.
    From the projectile equations, the values included are the angle, velocity, x distance, y distance, and time. I do not know what is the relation of the velocity of the bird to the projectile equations.

    Re: projectile

    So the stone flies in a parabola
    Drawn across this, half way up, you have the flight of the bird from the point that the stone was going up to the point it was coming back down.

    It might help to sketch a graph of displacement / time for the stone and the bird
