1. For women's volleyball the top of the net is 2.24m above the floor and the endline is 9.00m from the net. Using a jump serve, a player strikes the ball at a point 3.00 m above the floor and 8.00m (horizontally) from the net. If the initial velocity of the ball is horizontal and directed perpendicular to the endline, (a) calculate the minimum initial speed the ball must have to clear the net. (b) calculate the maximum initial speed the ball can have to stay inside the court.
