a girl and a boy are pulling heavy crate at the same time with 10 units of force each what is the net force acting on the object
Answer:
The net force acting on the object depends on the direction of the force that is applied by the boy and girl.
Explanation:
The net force of an object is the magnitude of the total vector force experienced by the object. Since it a vector force, the direction plays a great role in summing the forces.
From the problem, it is only stated that there are two forces that affects the crate, the force from the boy, and the force from the girl, both having the same magnitude, which is 10 unit of force.
Let us say that the crate is placed on the ground. If this is the scenario, aside from the force from the boy and girl, we can also consider the normal force (normal force direction: upward) acting on the crate, and this normal force should be included in computing the net force. But since we are not given with the value of the normal force, it is safe for us to neglect it.
Focusing on what is given in the problem, the answer to the question may vary depending on the direction of the force given by the boy and girl.
If the boy and the girl pulls the heavy crate on the same side, then we just add their forces. This will give us 10 units of force + 10 unit of force.
Hence, if the boy and girl pulls the crate at the same direction, the net force acting on the object is 20 units of force.
If the boy and the girl pulls the heavy crate on the opposite side, then we just subtract their forces since the direction of pull is opposing each other. This will give us 10 units of force - 10 unit of force.
Hence, if the boy and girl pulls the crate at different direction, the net force acting on the object is 0 units of force.
