Max RANGE of a projectile thrown from the top of a ramp.

  1. Aug 29, 2011 #1
    1. The problem statement, all variables and given/known data

    A projectile is thrown from the top of the ramp. Find the angle [itex]\theta[/itex] of the throw that gives a max range R down the ramp. [itex]\phi[/itex] is the angle made from the base of the ramp to the x-axis.

    2. The attempt at a solution

    Tried a number of times but failed to get anything that seemed moderately appropriate, i.e. getting long equations that are obviously too complex to be the answer.

    Appreciate the help.

    Thanks.

    Did you use a trig identity to simplify it?
