Formula:
Gravitational Potential Energy (PE) = mass (m) * acceleration due to gravity (g) * height (h)
Given:
* mass (m) = 742 kg
* acceleration due to gravity (g) = 9.8 m/s² (approximately)
* height (h) = 9 m
Calculation:
PE = 742 kg * 9.8 m/s² * 9 m
PE = 65,365.6 J (Joules)
Answer:
The gravitational potential energy of the wrecking ball is approximately 65,365.6 Joules.
