Newton's 2nd law of motion:
Force = (mass) x (acceleration)
= (0.314 kg) x (164 m/s²)
= 51.5 newtons
(about 11.6 pounds) .
Notice that the ball is only accelerating while it's in contact with the racket.
The instant the ball loses contact with the racket, it stops accelerating, and
sails off in a straight line at whatever speed it had when it left the strings.
It’s b all objects with mass experience gravitational attraction I hope this helps
-- Radio waves. (To hear the weather while I'm waking up.)
-- Light waves. (To see where the dog is so I don't step on him.)
-- Infrared waves. (To make my toast for breakfast.)
-- Microwaves. (To heat my oatmeal for breakfast. Also when I go in to my job as a microwave communications engineer.)
BBBBBBBB!!!!! ATOMIC MASSES :D
