An athlete in the Olympic games covers a distance of 100 m in 10 s. His kinetic energy can be estimated to be in the range:
- \(200 \sqrt{-500}\)
- \(2 \times 10^{5} \downharpoonleft-3 \times 10^{5} \downarrow\)
- \(2 \times 10^{5} \downharpoonleft-5 \times 10^{5} \downarrow\)
- \(2000 \sqrt{-5000}\)
Answer
(C) 2 10^ 5 -5 10^ 5
