Online homework screen showing a sprinter problem: 66.81 kg sprinter runs 54 m in 8.72 s; force 94.8926 N, power 269.5585 W at 2.0 s, and 539.1170 W at 4.0 s, each marked correct with receipt numbers.


Hello, not looking for much help on the problem, rather I am seeking someone to try and solve this problem and tell me I'm not crazy that the so called "correct" answers above are wrong.
