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
(1) $200 \mathrm{~J} - 500 \mathrm{~J}$
(2) $2 \times 10 ^ { 5 } \mathrm{~J} - 3 \times 10 ^ { 5 } \mathrm{~J}$
(3) $20,000 \mathrm{~J} - 50,000 \mathrm{~J}$
(4) $2,000 \mathrm{~J} - 5,000 \mathrm{~J}$
