Just need a complete solution and an answer that will answer these two questions. Please answer these... Thanks:(Also show the formula) :D
1) If a ball bounces two-thirds as far as it falls,how far will it travel before coming to rest if it is dropped from a height of a feet?
2)On each swing, a pendulum travels 80% as far as on its previous swing. If the first swing is 30cm long, how far has the pendulum by the time it comes to rest?

1)
travel=1+2/3+(2/3)^2+...+(2/3)^n=3*[1-…
if n is unlimited
then travel=3 feet
2)
far=30*[1-(80%)^(n+1)]/[1-80%]
if n is unlimited
then far=30/20%=150 cm
travel=1+2/3+(2/3)^2+...+(2/3)^n=3*[1-…
if n is unlimited
then travel=3 feet

far=30*[1-(80%)^(n+1)]/[1-80%]
