Understanding the Concepts
* Work: Work is done when a force causes an object to move a certain distance. The formula for work is:
Work (W) = Force (F) x Distance (d)
* Force due to gravity: The force of gravity on an object is its weight, which is calculated by:
Force (F) = Mass (m) x Acceleration due to gravity (g)
Where 'g' is approximately 9.8 m/s²
Solving the Problem
1. Find the force:
* We know the work done (W = 162 J) and the distance (d = 0.1 m).
* Using the work formula, we can find the force:
F = W / d = 162 J / 0.1 m = 1620 N
2. Find the mass:
* We know the force (F = 1620 N) and the acceleration due to gravity (g = 9.8 m/s²).
* Using the force due to gravity formula, we can find the mass:
m = F / g = 1620 N / 9.8 m/s² = 165.3 kg (approximately)
Therefore, the mass of the person is approximately 165.3 kg.
