How to Calculate the Weight of a Barbell?

What is the weight of a barbell if a weightlifter lifts a barbell of mass 50 kg to a height of 2m in 3s?

a) 490N

Answer:

The weight of the barbell is 490N.

Calculating the weight of a barbell involves using the formula: Weight = mass x gravity. In this case, the mass of the barbell is 50 kg and the acceleration due to gravity (g) is 9.8 m/s².

By substituting the values into the formula, we get:

Weight = 50 kg x 9.8 m/s² = 490N

Therefore, the weight of the barbell is 490 Newtons.
