To calculate the potential energy of the wood on the carpenter's shoulder, we can use the equation:
Potential Energy = mass * acceleration due to gravity * height
Given:
mass (m) = 20 kg
acceleration due to gravity (g) = 9.8 m/s^2
height (h) = 1.5 m
Potential Energy = 20 kg * 9.8 m/s^2 * 1.5 m
Potential Energy = 294 Joules
Therefore, the wood's potential energy on the carpenter's shoulder is 294 Joules.
