Quandaries
and Queries 

Name: Eman Question: Hi there ~ I am doing my AS levels and have come across something that I am stuck with. I planned to ignore it but it keeps coming up literally everywhere, so I guess its important to know how to do it. I’d really appreciate it if you would please *explain* HOW to do it, because I have the solution to one of the sums of the type, but its beyond my understanding as to what exactly I am to do and WHY. Here it is: Q : When a child’s ball is dropped from a height h metres on to a hard, flat floor, it rebounds to a height of 3/5h metres. The ball is dropped initially from a height of 1.2m.
Thank you so much for helping. You guys are doing a great job. :) I am doing this course through correspondence so would really appreciate the help. Thanks again. Eman. 

Hi Eman, If the ball starts at height h meters then in one bounce it goes to the floor and then bonces up ^{3}/_{5}h meters for a total distance travelled of After 9 bounces the ball has travelled For part 3, you have ^{8}/_{5}h meters times a geometric series Penny
