A horizontal push of 197 N is applied to a 49.1 kg crate to slide it along a level floor. The crate is accelerating at [tex]3.337 \, \text{m/s}^2[/tex] (speeding up).

What is the magnitude of the kinetic friction force between the crate and the floor?

Answer :

The magnitude of the kinetic friction force between the crate and the floor is 33.15 N.

Kinetic frictional force

The magnitude of kinetic frictional force is determined by applying Newton's second law of motion as shown below;

F - Ff = ma

where;

  • Ff is kinetic frictional force
  • a is acceleration of the crate
  • F is the applied force

Subsitute the given parameters and solve for kinectic frictional force

197 - Ff = 49.1(3.337)

197 - Ff = 163.85

Ff = 33.15 N

Thus, the magnitude of the kinetic friction force between the crate and the floor is 33.15 N.
