Maximum Height of Projectile Using Cons. of Energy

  1. Sep 26, 2008 #1
    1. The problem statement, all variables and given/known data

    A projectile is launched with a speed of 45 m/s at an angle of 56° above the horizontal. Use conservation of energy to find the maximum height reached by the projectile during its flight.

    2. Relevant equations

    3. The attempt at a solution
    I thought in this equation that the angle wouldn't matter, but I know I'm wrong. I thought you could just plug it the numbers to the manipulated formula h=.5v^2/g. Please help! thanks

    Yes the angle matters. You need to consider the vertical component of the initial velocity.
