SUMMARY
The power output of a bodybuilder lifting 150 kg to a height of 2.2 m in 1.3 seconds can be calculated using the formula for power, which is work done divided by time. The work done is determined by the equation Work = mass × gravity × height. Using the standard acceleration due to gravity (9.81 m/s²), the work done is 3,234.6 Joules. Dividing this by the time of 1.3 seconds yields a power output of 2,487 Watts, which converts to approximately 3.34 horsepower (1 hp = 746 W).
