    Projectile Motion Problems: Calculating Maximum Angles and Heights

    Dick, why is it that I have to find the derivative of r(t)^2? the distance is r(t) so shouldn't I derive r(t) with respect to t and not r(t)^2?

    Finding the Maximum Angle for Projectile Motion of a Cannon

    why is the g in the equation for y squared? shouldn't g just be to the first power?
