Stan the strongman lifts a 524 kg dumbbell from the floor to 1.69 meters above the floor at a constant velocity.
How much energy does it take Stan to lift the dumbbell?
To calculate the energy required to lift the dumbbell, we need to consider the gravitational potential energy. The formula to calculate gravitational potential energy is given by:
Potential Energy = mass * gravitational acceleration * height
Here, the mass of the dumbbell is 524 kg, the height is 1.69 meters, and the gravitational acceleration is approximately 9.8 m/s^2.
Plugging in these values into the formula, we get:
Potential Energy = 524 kg * 9.8 m/s^2 * 1.69 meters
Evaluating the expression, we find that the potential energy required to lift the dumbbell is approximately 8591.432 Joules.
