b.) A canon ball is projected vertically upward from a point with an initial speed of 49ms-. The point is situated at the edge of a cliff 180m above the sea. On the way down, the canon ball just misses the cliff. In the vertical fall, the canon ball will have a terminal speed of 70ms . Assuming that air resistance is proportional to the square of the speed find: i) How high the ball rises. ii) How long it is in the air before it enters the sea.
