Homework Help: Initial Velocity Given Distance, Angle, and Initial Height

  1. Nov 24, 2009 #1
    1. The problem statement, all variables and given/known data
    Given your assigned projectile launcher determine the muzzle velocity.

    angle of launcher = 45degrees
    distance to bottom of barrel = 25.6 cm
    distance traveled when fired = 119.2cm

    Ignore Air resistance

    2. Relevant equations

    I don't know where to start since I have an angle.

    3. The attempt at a solution

    I don't know where to begin since the projectile is basically starting from a platform at an angle.

    Start with the Kinematic equations of motion.

    Since the cannon ball is fired at an angle, it should have 2 sets of equation (vertical and horizontal).

    That should set you off. If you need help, reply back here and I will give you the equations with an explanation.
