Suppose that a ball has a rebound percentage of 75 and the ball is dropped from a height of 5ft onto the concrete below. Make a table of the data.
Write a recursive rule for the data.
Write a closedform function rule for the data.
What would the height of the 5th bounce of this ball be if the initial drop height is 10 ft above ground?

Is 75% the height (energy) recovery factor or the velocity recovery factor? The latter is called the coefficient of restitution.
