On Earth, what is the weight of a large screen TV that has a mass of 82 kg? (Answer to the nearest hundredth)

Answer 1

Weight is the force of gravity on an object. Therefore the equation for this is:

F = ma

with a = 9.8 m/s²

To determine the weight of a 70 kg person, we substitute in the values:

Weight = F = 82 kg x 9.8 m/s² = 803.6 kg(m)/s²

The unit kg(m)/s² is also known as a Newton and rounding to the nearest hundredth, the answer becomes 803.60 N.
