An Olympic bodybuilder lifts a 1325 kg weight a vertical distance of 2.5 m off the ground. What potential energy do the weights have now?
To calculate the potential energy of the weights lifted by the Olympic bodybuilder, you can use the formula: Potential Energy = Mass × Gravity × Height.
1. Start by identifying the variables given in the problem:
- Mass (m) = 1325 kg
- Height (h) = 2.5 m
- Gravity (g) = 9.8 m/s² (acceleration due to gravity on Earth)
2. Plug the values into the formula:
Potential Energy = Mass × Gravity × Height
Potential Energy = 1325 kg × 9.8 m/s² × 2.5 m
3. Calculate the potential energy:
Potential Energy = 32,450 J (Joules)
Therefore, the weights have a potential energy of 32,450 Joules when lifted by the Olympic bodybuilder.
To determine the potential energy of the weights, you can use the formula:
Potential Energy = Mass * Gravity * Height
The mass of the weights is given as 1325 kg, the acceleration due to gravity is 9.8 m/s^2, and the height is 2.5 m.
Plugging in these values into the formula:
Potential Energy = 1325 kg * 9.8 m/s^2 * 2.5 m
Potential Energy = 32,573.5 Joules
Therefore, the potential energy of the weights is 32,573.5 Joules.
The potential energy of an object is given by the formula:
Potential Energy = mass * gravity * height
where mass is the mass of the object, gravity is the acceleration due to gravity, and height is the vertical distance the object is lifted.
Here, the mass lifted is 1325 kg, the height lifted is 2.5 m, and the acceleration due to gravity is 9.8 m/s^2.
So, the potential energy of the weights is given by:
Potential Energy = 1325 kg * 9.8 m/s^2 * 2.5 m
= 32,512.5 J
Therefore, the potential energy of the weights after being lifted 2.5 m off the ground is 32,512.5 J.
