The magnitude of the force that must be applied to push the book across the desk is 3.97 N.

The given parameters;

  • mass, m = 1.35 kg
  • coefficient of friction, μ = 0.3

The acceleration of the book across the desk is calculated as follows;

a = μg

where;

  • g is acceleration due to gravity

a = 0.3 x 9.8

a = 2.94 m/s²

The magnitude of the force that must be applied is calculated as follows;

F = ma

F = 1.35 x 2.94

F = 3.97 N

Thus, the magnitude of the force that must be applied to push the book across the desk is 3.97 N.
