Hi, I am not going to ask you to do my homework, since i have done them myself. I just want your help to double check my questions. 1. A tennis ball is thrown horizontally with an initial velocity of 14.5 m/s from a height of 1.4 m above the ground. Determine the following: (a) the time the ball spends in the air. (0.53 s) (b) the velocity with which the ball impacts the ground. (15 m/s [20 degree below horizonal]) 2. You are trying to throw a ball over a 3.0 m high fence. You throw the ball from a height of 1.0 m with an initial velocity of 27 m/s 50° above the horizontal. Determine the following: (a) the maximum height of the ball. (23.5 m) (b) the time the ball spends in the air. (4.33 s) 3. An artillery gun can fire a shell at an initial velocity of 1700 m/s at an angle of 55° above the horizontal. Determine the following: (a) the time the shell spends in the air. (Is the answer appx. 284 s) If i am missing any directions, please let me know. Thanks! I really appreciate it!
