Final answer:
The weight of a barbell is calculated using the formula for weight (w=mg). However, in terms of stating the 'weight' in the everyday sense of the term, we refer to the mass of the object, so a 115 kg barbell will remain 115 kg no matter what.
Explanation:
The weight of an object is a measure of the force of gravity acting on it, and it is calculated with the formula: w = mg, where 'm' represents the mass of the object and 'g' is the acceleration due to gravity. On Earth, g is approximately 9.80 m/s².
In this case, the mass of the barbell is stated as 115 kg. Therefore, we simply substitute this into our formula: w = 115 kg * 9.80 m/s². However, it's important to note that in physics, the term 'weight' is typically used to refer to the force that gravity exerts on an object, and this is measured in Newtons, not kilograms. When we say that something 'weighs' 115 kg, we are actually referring to its mass.
Thus, while you might see options to indicate different weights for the same mass of the barbell, the mass of the barbell remains 115 kg
