When the SuperBall® was introduced in the 1960’s, kids across the United States were amazed that these hard rubber balls could bounce to 90% of the height from which they were dropped.
a. Is this problem an example of a geometric series or an arithmetic series? Support your answer mathematically by applying the concepts from this unit.
b. If a SuperBall® is dropped from a height of 2m, how far does it travel by the time it hits the ground for the tenth time? (Hint: The ball goes down to the first bounce, then up and down thereafter.)

a) its a geometric series...forgot how to proove it though...lol
Ha ha ok thanks... i thought it was a geometric series I can figure the proving part out....
the reason why its geometric is because the value doesnt change linearly...its always a percentage (90 in this case...)
