SUMMARY
A 100kg man climbing a vertical 10m ladder in 12 seconds performs work calculated using the equation W = mgh, where g is the acceleration due to gravity (9.81 m/s²). The total work done by the man is 9800 Joules. To find the man's power output, the formula P = W/t is used, resulting in a power output of approximately 816.67 Watts.
