Prove that the trajectory of a projectile is parabolic, having the form y= ax + bx2. To obtain this expression, solve the equation x=voxt for t and substitute it into the expression for y=voyt- (1/2)gt^2. (These equations describe the x and y positions of a projectile that starts at the origin.) You should obtain an equation of the form y=ax+bx2 where a and b are constants.
