# Find net force, given velocity?

• JettyZ
In summary, net force is the overall force acting on an object, taking into account both magnitude and direction. It is calculated using the formula Fnet = m x a, where Fnet is the net force, m is the mass, and a is the acceleration. Net force can be negative when the individual forces are in opposite directions, and changes in velocity can affect net force if mass or acceleration changes. Net force can also be greater than the individual forces when they are acting in the same direction.

## The Attempt at a Solution

a)
Fnet=(2250cos(35)) * 2 - 1250
Fnet=+593 N [E]

b)
I have solved part a, but I don't understand how to approach part b.

The problem apparently means that the barge is later moving at a constant velocity of 2.5 m/s [E].

## 1. What is net force?

Net force is the overall force acting on an object, taking into account both magnitude and direction. It is the sum of all the individual forces acting on an object.

## 2. How is net force calculated?

To find net force, we use the formula Fnet = m x a, where Fnet is the net force, m is the mass of the object, and a is the acceleration. This formula takes into account both the mass and acceleration of the object.

## 3. Can net force be negative?

Yes, net force can be negative. This simply indicates that the forces acting on the object are in opposite directions, resulting in a net force that is smaller than the individual forces.

## 4. How does velocity affect net force?

Velocity does not directly affect net force. However, it is a component of the formula for calculating net force (Fnet = m x a). Therefore, changes in velocity can result in changes in net force if the mass or acceleration of the object also change.

## 5. Can net force be greater than the individual forces?

Yes, net force can be greater than the individual forces acting on an object. This occurs when the forces are acting in the same direction, resulting in a combined force that is larger than either individual force.
