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 arrows are in the opposite direction, then they subtract. Vectors are directed numbers. A force East is a negative force West.
To find the acceleration and net force (Fnet) acting on the object, you need to consider the forces acting on it. In this case, you have two arrows pointing in opposite directions, which we can assume are forces acting on the object.
First, assign a direction as positive. Let's assume that one arrow is pointing to the right, so we can consider that as the positive direction. The other arrow pointing in the opposite direction would then be the negative direction.
Since the two arrows are pointing in opposite directions, they can be considered forces in opposite directions as well. In this case, the force pointing to the right (positive direction) can be represented by a positive value, and the force pointing to the left (negative direction) can be represented by a negative value.
Let's say the force pointing to the right is F1, and the force pointing to the left is F2. Since they have opposite directions, we can write the equation for net force as:
Fnet = F1 + F2
In this scenario, we don't have any information about the magnitudes of the forces (F1 and F2), other than the mass of the object (10 kg). Therefore, without specifying any values for the forces, it is not possible to calculate the net force or the acceleration.
To find the acceleration, you would need the net force acting on the object and the mass of the object. The equation relating these quantities is given by Newton's second law:
Fnet = m * a
Where Fnet is the net force, m is the mass, and a is the acceleration. Rearranging the equation, we can solve for acceleration:
a = Fnet / m
For this specific scenario, since we don't know the forces, we can't calculate the net force or the acceleration. However, if you have specific values for the forces (F1 and F2), you can substitute them into the equations to find the net force and acceleration.
