A student has a cannon that can fire a cannonball at speeds up to 93.0mph. The students wants to determine the maximum range of the cannon and if she could hit a target on the ground as shown. Neglect drag and the initial height of the cannonball. At what angle should the cannonball be fired to achieve maximum range? When fired at this angle, how long will the cannonball remain in the air? What is the cannon's maximum range? m If the student adjusted the angle of the cannon, could the cannon hit a target located 190m from the cannon (measured along the ground)
