Answer 2

Problem Statement:

A body with a mass of 600g is moving horizontally. A force of 1.2 Newtons is applied to the body. Determine the coefficient of friction.

Solution:

To determine the coefficient of friction, we need to use Newton's second law of motion, which states that the net force acting on an object is equal to the product of its mass and acceleration. In this case, the net force is the applied force minus the force of friction.

Let's denote the coefficient of friction as μ and the acceleration of the body as a. The force of friction can be calculated using the equation:

Frictional force = μ * Normal force

The normal force is the force exerted by a surface to support the weight of an object resting on it. In this case, since the body is moving horizontally, the normal force is equal to the weight of the body, which can be calculated as:

Normal force = mass * gravity

where the mass is given as 600g and gravity is the acceleration due to gravity, approximately 9.8 m/s^2.

Now, we can rewrite the equation for the frictional force as:

Frictional force = μ * mass * gravity

Since the net force acting on the body is the applied force minus the force of friction, we have:

Net force = Applied force - Frictional force

Using Newton's second law, we can express the net force as:

Net force = mass * acceleration

Setting the equations for the net force and frictional force equal to each other, we get:

mass * acceleration = Applied force - μ * mass * gravity

Now, we can solve for the acceleration:

acceleration = (Applied force - μ * mass * gravity) / mass

Given that the mass is 600g (0.6kg) and the applied force is 1.2N, we can substitute these values into the equation to solve for the acceleration.

Finally, once we have the acceleration, we can determine the coefficient of friction using the equation:

μ = (Applied force - mass * acceleration) / (mass * gravity)

Let's calculate the coefficient of friction using the given values.
