A 35kg crate slides across floor which experts a 110N friction force on it. What horizontal force is required to move the crate at a steady speed across the floor.

Answer:

The froce needed is 110 N

Explanation:

We need to make and sketch of the crate and the forces acting on it.

Since the movement is a constant velocity there is no acceleration, therefore, Newton's second law m*a = 0.

And from the equation deducted, we can appreciate that the opposite force to the friction force is the one that it's needed to move the crate at constant velocity.
