Question:
If a ball is "soft," it will spend more time in contact with the floor and won't rebound as high as it is supposed to. The force on the floor of the "soft" ball is the force on the floor of a "normal" ball.
A. Greater than B. The same as C. Less than Tennis balls are tested by being dropped from a height of \(2.5 \mathrm{~m}\) onto a concrete floor. The \(57 \mathrm{~g}\) ball hits the ground, compresses, then rebounds. A ball will be accepted for play if it rebounds to a height of about \(1.4 \mathrm{~m}\); it will be rejected if the bounce height is much more or much less than this.
