Homework Help: How high can it fly?

  1. Jan 27, 2009 #1
    Can anyone please help me figure this question out;

    A senior physics class conducting a research project on projectile motion constructs a device that can launch a cricket ball. The launching device is designed so that the ball can be launched at ground level with an initial velocity of 28m/s at an angle of 30 degrees to the horizontal. What is the maximum height that is achieved by the ball, given that the acceleration due to gravity is 9.8m/s and there is no air resistance?

    Witch kinematics equations do you think would be a good start?
