Homework Help: Projectile motion

  1. Nov 29, 2007 #1
    1. The problem statement, all variables and given/known data
    If at height of 40 m the direction of motion of a projectile makes an angle 45 degrees with
    the horizontal, then what is its initial velocity and angle of projection?

    2. Relevant equations

    3. The attempt at a solution

    I dont really know how much help i can be but from what i remember you the x and y times will be the same. So 40m and the acceleration of gravity with the angles are what you need to solve the problem
