Answer:
The force on the book is 250N.
Step-by-step explanation:
Newton's second law states that the equation for the force is:
[tex]F = ma[/tex]
In which m is the mass, in kilograms, and a is the acceleration, in m/s². F is the force measured in N.
In this question:
[tex]m = 50, a = 5[/tex]
So
[tex]F = ma = 50*5 = 250[/tex]
The force on the book is 250N.
