How do you find acceleration and Fnet for a diagram containing only one object with a mass, like say 10kg, and two arrows going in the opposite directions(horizontally) with thier tips touching each side of the object. **NOTE: there are no other numbers other than the mass.

If the forces are in opposite directions, they subtract. Force is a directed number (vector) so direction matters.

To find the acceleration and the net force (Fnet) acting on the object, you need to consider the forces applied to the object and apply Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (Fnet = m × a).

In this case, there are two forces acting on the object in opposite directions, but we are not given any numerical values for the forces. However, we can still analyze the situation conceptually.

Since the forces are in opposite directions, they will subtract from each other. The force that has a greater magnitude will determine the direction of the net force.

Let's take an example:
Let's assume one arrow applies a force of 7 newtons to the right (positive direction), and the other arrow applies a force of 5 newtons to the left (negative direction).

Since the forces are in opposite directions, we subtract the smaller magnitude from the larger magnitude.
Therefore, the net force (Fnet) will be 7 N - 5 N = 2 N to the right.

Now, to find the acceleration, we apply Newton's second law: Fnet = m × a.

Since we are given the mass of the object as 10 kg, we can substitute that value into the equation:
2 N = 10 kg × a.

To solve for acceleration (a), we divide both sides of the equation by the mass (10 kg):
a = 2 N / 10 kg.

Hence, the acceleration of the object is 0.2 m/s^2 to the right.

Please note that without any numerical values for the forces, we can only provide a conceptual explanation based on assumed values.
