It was a children versus grown-ups competition at school. one event required the adult to throw a basketball as far as he could. when it was the child's turn, he had to throw a baseball instead. the event coordinator said, "it's only fair! " based on newton's laws, was this event fair?
(a)yes, because an adult can apply more force than a child can. making the adult's object bigger than the child's object to even out the acceleration.
(b)no, because a basketball is bigger than a baseball, and objects that are bigger accelerate slower.
(c)yes, because acceleration doesn't depend on the size of the object.
(d)no, because you must have the same size object in a competition.
