Answer:
89.263 m I couldn't remember the easist way of doing this type of summation problem. I used brute force. a spread sheet would have been quicker
Step-by-step explanation: 6 17 22 16
Event Formula Calculation Running Summation
1 20 20 20
2 20(4/5) 16 36
3 20(4/5)(4/5) 12.8 48.8
4 20(4/5)(4/5)(4/5) 10.24 59.04
5 20(4/5)^4 8.192 67.232
6 20(4/5)^5 6.554 73.786
7 20(4/5)^6 5.453 79.028
8 20(4/5)^7 4.194 82.223
9 20(4/5)^8 3.355 86.578
10 20(4/5)^9 2.684 89.263
add the results from each swing
I got 89.263 meters
