Question

What is the weight, on Earth, of a book with a mass of 1.5 kg

Answer 1

The answer is
D) 14.7 N

Answer 2

Answer: 14.7 N

Explanation:

The weight of an object on Earth is given by

$W=mg$

where

m is the mass of the object

$g=9.81 m/s^2$ is the acceleration due to gravity on Earth's surface

In this problem, we have a book of mass m=1.5 kg, so its weight is given by

$W=mg=(1.5 kg)(9.81 m/s^2)=14.7 N$
