Two dogs are pulling on opposite ends of a bone. One dog pulls to the right with a force of 50 N while the other pulls to the left with a force of 40 N. Are the forces on the bone balanced or unbalanced? How do you know? What is the net force on the bone? Would the bone's velocity change? Why?
To determine whether the forces on the bone are balanced or unbalanced, we need to compare the magnitudes and directions of the forces acting on it.
In this case, the dog pulling to the right applies a force of 50 N, while the dog pulling to the left applies a force of 40 N. Since the forces are in opposite directions, we can subtract the smaller force from the larger force to find out the net force.
Net force = 50 N - 40 N
Net force = 10 N
The net force on the bone is 10 N. Since the net force is not zero, we can conclude that the forces on the bone are unbalanced.
The bone's velocity will change because an unbalanced force is acting on it. According to Newton's second law of motion, when an unbalanced force acts on an object, it causes the object to accelerate in the direction of the net force. In this case, the bone will start moving in the direction of the larger force, which is towards the right.
