A box is pulled across the floor a at constant speed it is pulled horizontal force of 48 N
NO
More data needed.
To determine the force required to pull the box across the floor at a constant speed, we need to consider the concept of friction.
Friction is the force opposing motion between two surfaces in contact. In this case, the box is being pulled horizontally, so we are dealing with kinetic friction.
First, we need to know the coefficient of kinetic friction (μk) between the box and the floor. The coefficient of kinetic friction depends on the nature of the surfaces in contact. Let's assume the coefficient of kinetic friction is μk.
The formula to calculate the force of kinetic friction is given by:
Friction = μk * Normal force
The normal force is the force exerted by the surface perpendicular to the box. Since the box is being pulled horizontally, the normal force cancels out the vertical force due to gravity (mg).
Therefore, the force required to pull the box at a constant speed is equal to the force of kinetic friction, which can be calculated as:
Force = μk * (mg)
where m is the mass of the box and g is the acceleration due to gravity (approximately 9.8 m/s^2).
Using the given horizontal force of 48 N, we can set up an equation:
48 N = μk * (m * 9.8 m/s^2)
To solve for μk, we need additional information, such as the mass of the box or any other relevant information about the system.
