What information do you need to know to calculate how much work it takes to lift a 160N barbell?
A. The height the barbell is being lifted
B. The shape of the barbell
C. The speed at which the barbell is lifted
D. The strength of the person doing the lifting
Final answer: To calculate how much work it takes to lift a 160N barbell, you need to know the height the barbell is being lifted.
Answer:
To calculate how much work it takes to lift a 160N barbell, you need to know the height the barbell is being lifted.
When calculating the work done in lifting a barbell, you need to consider the height at which the barbell is being lifted. The work done in lifting an object is determined by the formula: work = force x distance. In this case, the force is the weight of the barbell, which is 160N, and the distance is the height the barbell is being lifted.
By knowing the height at which the barbell is lifted, you can calculate the work done accurately. This information is crucial in determining the amount of energy expended in lifting the barbell to a certain height.
Understanding how to calculate work in lifting a barbell helps in assessing the amount of effort required and the energy consumed during weightlifting exercises. It is essential to have the necessary information, such as the weight of the barbell and the height it is being lifted, to make accurate calculations and track progress in strength training.
