A cannon is placed on a hillside pointing up the hill, where the hill is at an angle a Pi/4 to the horizontal.
The cannon points at an angle Pi/6 to the slope.
and a shot is red uphill with initial speed v0.
(i) Find the maximum value of the distance between the cannon ball and the slope in the direction normal to the slope.
(ii) Find where the ball lands.
