Science and Mathematics Assignment Bouncing Ball Term 1

Science and Mathematics Assignment ‘Bouncing Ball’ Term 1 2014

Problem A A basketball is dropped from a height of 200 cm. It bounced a solid surface to a height than can be expressed as the drop height divided by 2. What is the final bounce height? Problem Solving 200 ÷ 2 = 100 Drop height 200 cm Bounce height 100 cm

Problem B Calculate what the bounce height will be if the ball is dropped from half the original height in the previous question. 100 cm Drop height 50 cm Bounce height Problem Solving 100÷ 2 =50

Problem C A super bouncy ball was recently advertised as being able to bounce very high. After dropping it from a height of 25 meters, the ball lost only 25% of its starting height. To what height did the ball bounce? Drop Height 25 meters drop height 18. 75 meters Bounce Height Problem Solving Simplify 25/100 to 25= 25/4. Then divide the 25/4= 6. 25 m. Lastly subtract the drop height 25 m to 6. 25 m. Final answer= 18. 75 m

Extension Question If a super bouncy ball loses 50% of its start height on every bounce, how many bounces will it take before it bounces less than a centimetre if it is dropped from 100 cm 100 cm Drop Height 7 bounces until less than 1 cm Problem Solving Divide the drop height 100 cm by 2 and divide the answer by 2 also. Keep doing this until you reach under 1 cm
