A ball is dropped from a height of 3 ft. The elasticity of the ball is such that it always bounces up onethird the distance it has fallen.
(a) Find the total distance the ball has traveled at the instant it hits the ground the fourth time. (Enter your answer as an improper fraction.)

Best ResponseYou've already chosen the best response.0This how I solved it: Suppose K=1/3 first time d1=3 second time d2=3*K=1 Third time d3=1*k=1/3 Forth time d4=K(1/3)=1/9 Now adding up d1+d2+d3+d4, we get the total distance d=40/9

Best ResponseYou've already chosen the best response.0Suppose K=1/3 first time d1=3 second time d2=2*(3*K)=2 Third time d3=2*(2*k)=4/3 Forth time d4=2*K(4/3)=8/9 Now adding up d1+d2+d3+d4, we get the total distance d=65/9. Is that correct. Hopefully yes

Best ResponseYou've already chosen the best response.0no that was the answer to a similar problem. I thought if i gave you that answer then it might help you figure out the the problem

Best ResponseYou've already chosen the best response.0You start at 3 fall 3 rise (3 * 1.3) =1 fall 1 rise ( 1 * 1/3) = 1/3 fall 1/3 rise (1/3 * 1/3) = 1/9 fall 1/9 I stop at 1/9 because at fall 1/9 is the 4ht instant I hit the ground. add 3 + 1 + 1 + 1/3 + 1/3 + 1/9 + 1/9 5+ 2/3 + 2/9 5 + 6/9 + 2/9 5 + 8/9 45/9 + 8/9 53/9

Best ResponseYou've already chosen the best response.0The formula of the the that is droped from 9 ft is 18(1/3)^n3. so i assume that the ball droped from 3ft had a similar formula...

Best ResponseYou've already chosen the best response.0I can derive a formula but it will be hard since you start from the top and you want to know the distance it travels on the fourth hit to the floor.

Best ResponseYou've already chosen the best response.0btw the formula you use gives you 53/3 not 53/9 for the 4th hit.
