Final answer:
The mass of the barbell lifted by Naim Suleimangolu, which has a potential energy of 3.04 x 10³ J when raised 1.70 m above the floor, is approximately 176.47 kg.
Step-by-step explanation:
The question involves calculating the mass of a barbell based on its potential energy when lifted to a certain height by a weightlifter. To solve this, we can use the formula for gravitational potential energy ( PE = mgh ), where PE is the potential energy, m is the mass, g is the acceleration due to gravity (9.80 m/s² on Earth), and h is the height.
The potential energy given in the question is 3.04 x 10³ J (joules), and the height is 1.70 m. We can rearrange the formula to solve for mass: m = PE / (gh). Plugging in the known values, we get:
m = (3.04 x 10³ J) / (9.80 m/s² * 1.70 m)
m ≈ 176.47 kg
Therefore, the mass of the barbell lifted by Naim Suleimangolu is approximately 176.47 kg.
