Answer:
[tex]\boxed {\tt 14.7 \ Newtons}[/tex]
Explanation:
Weight is force due to gravity.
The formula for weight is:
[tex]W=m*g[/tex]
where m is the mass and g is the acceleration of gravity.
On Earth, the acceleration due to gravity is 9.8 meters per seconds squared.
The mass of the book is 1.5 kilograms. Therefore:
[tex]m= 1.5 \ kg \\g=9.8 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]W= 1.5 \ kg *9.8 \ m/s^2[/tex]
Multiply.
[tex]W=14.7 \ kg*m/s^2[/tex]
1 kg meter per second squared is equal to 1 Newton, so our answer of 14.7 kg*m/s² is equal to 14.7 Newtons.
[tex]W=14.7 \ N[/tex]
The weight of a 1.5 kilogram book on Earth is 14.7 Newtons.
