Question

A 10-newton force is applied to a 2-kg block. The block slides across the floor at a constant speed of 5 m/s. What is a valid conclusion from this situation?

Answer 1

Explanation :

It is given that, a 10-Newton force is applied to a 2-kg block. The block slides across the floor at a constant speed of 5 m/s.

The block is sliding with a constant speed. This shows the acceleration of the block is zero.

When an object slides that means the force acting on it is unbalanced i.e. the object will move in a particular direction.

The frictional force will also act on the box. So, we can say that the 10 N force is an unbalanced force.

Answer 2

A valid conclusion is that the floor is frictionless because it slide at a constant speed. This means no force is opposing the applied force to box. Another conclusion can be made is that the box also has a momentum of 10 kg m/s
