An Olympian lifts a 1,375-kilogram set of weights a vertical distance of 2 meters in the weightlifting event. The force of gravity equals 9.8 m/s2. What is the potential energy of the weights?
m * g * h
To calculate the potential energy of the weights, we can use the formula:
Potential energy = mass × gravity × height
Given:
Mass of the weights (m) = 1,375 kilograms
Height (h) = 2 meters
Force of gravity (g) = 9.8 m/s^2
Substituting the given values into the formula:
Potential energy = 1,375 kg × 9.8 m/s^2 × 2 meters
Calculating this expression:
Potential energy = 26,900 joules
Therefore, the potential energy of the weights is 26,900 joules.
To calculate the potential energy of the weights, we can use the formula:
Potential energy = Mass × Gravity × Height
Given:
Mass = 1,375 kilograms
Gravity = 9.8 m/s^2
Height = 2 meters
Substituting the given values into the formula, we get:
Potential energy = 1,375 kg × 9.8 m/s^2 × 2 m
Now, let's perform the calculation:
Potential energy = 1,375 × 9.8 × 2
Potential energy = 26,950 joules
Therefore, the potential energy of the weights in this scenario is 26,950 joules.
