You have designed a tennis ball cannon with a muzzle velocity of 50 m/s. you want to land a tennis ball in a swimming pool 200 m away. at what angle to the horizontal do you need to aim the gun? round your answer to the nearest degree.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
