1.A ball is dropped from a height of 2.0, to a floor. After each bounce, the ball rises to 63% of its previous height
What is the total vertical distance the ball has travelled after 5 bounces?
2.An oil produces 25000 barrels of oil durign its first month of production. suppose its production drops by 5% each month
estimate the total production before the well runs dry

1. This depends upon whether you add vertical distance going up and going down. I will assume that is what they mean. It also depends upon whether you stop counting at the end of the fifth bounce.
2.00 m going down the first time
2*2.00*0.63 = 2.52 m going up and down on the first bounce
2*2.00*0.63^2 = 1.59 m going up and down on the second bounce.
etc. You can finish these and add them up yourself
2. 25000*(1 + .95 + .95^2 + .95^3 + ...)
If you don't want to add up a lot of terms, you can use the rule that the sum of this infinite series is
25000*/(1.95) = ?

Up and down means doubling the distance.
2 x 0.63 m is how far it rises after the first bounce
