A tennis ball may leave a top player's racket on the serve with a speed of 65.0 m/s. If the ball's mass is 0.0600 kg and it is in contact with the racket for 0.0300 s, what is the average force exerted on the ball? Would this force be enough to lift a person off the ground?

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

answer; how far out of place which the object finished relative to the starting location;

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
