Many games depend on how a ball bounces. For example, if different basketballs rebounded differently, one basketball would bounce differently off of a backboard than another would, and this could cause basketball players to miss their shots. For this reason, manufacturers have to make balls' bounciness conform to specific standards. Listed below are "bounciness " standards for different kinds of ball. Tennis balls: Must rebound approximately 111 cm when dropped from 200 cm. Soccer balls: Must rebound approximately 120 cm when dropped from 200 cm onto a steel plate. Basketballs: Must rebound approximately 53.5 inches when dropped from 72 inches onto a wooden floor. Squash balls: Must rebound approximately 29.5 inches when dropped from 100 inches onto a steel plate at 70∘F Discuss with your team how you can measure a ball's bounciness. Which ball listed above is the bounciest? Justify your answer.

    Basketball = 0.743

    Step-by-step explanation:

    Given

    Tennis:

    Starting Height = 200 cm

    Rebound Height = 111 cm

    Soccer Balls;

    Starting Height = 200 cm

    Rebound Height = 120 cm

    Basketball:

    Starting Height = 72 inches

    Rebound Height = 53.5 inches

    Squash:

    Starting Height = 100 inches

    Rebound Height = 29.5 inches

    For measuring the bounciness of a ball, one needs that starting Height of and the rebound Height of that ball which have been listed out above.

    Calculating the rebound ratio of each balls.

    Rebound Ratio = Rebound Height/Starting Height

    Tennis: 111/200 = 0.556

    Soccer Balls: 120/200 = 1.667

    Basketball: 53.5/72 = 0.743

    Squash: 29.5/100 = 0.295

    From the rebounding ratio calculated above, it can be seen that basketball has the highest rebound ratio of 0.743 and is the bounciest of all whole Squash has the least rebound of 0.295 ratio, hence it is the least bounce of all.
