Question

When a net force of 17.0 newtons is applied to a dictionary placed on a frictionless table, it accelerates by 3.75 meters/second2. What is the mass of the book?

Answer 1

F = ma
17 N = (3.75 m/s/s) m
m = 4.53 g

Answer 2

Answer : The mass of the book is 4.53 kg.

Explanation :

Force : It is defined as the product of mass of an object and acceleration of an object.

Formula used :

`Force=Mass* Acceleration`

Given:

Force = 17.0 N

Acceleration =
`3.75m/s^2`

Now put all the given values in this formula, we get:

`17.0N=Mass* 3.75m/s^2`

`Mass=4.53kg`

The unit of force is, N or
`kgm/s^2`

Therefore, the mass of the book is 4.53 kg.
