A rode is attached to block that has a weight 120N. When the rope exert an upward force N on the block what is the net force on the block?
What is the answer
What is 120-N?
To determine the net force on the block, we need to consider all the forces acting on it.
Given that the rope exerts an upward force of N on the block, we can assume that N represents the tension force in the rope.
The weight of the block is given as 120N, which is a downward force acting on the block due to gravity.
So, the net force is the vector sum of the tension force (upward force) and the weight of the block (downward force).
Net force = Tension force - Weight of block
Net force = N - 120N
Net force = N - 120N = -120N + N = -120N + 1N = -119N
Therefore, the net force on the block is -119N.
To determine the net force on the block, we need to consider the forces acting on it. In this case, we have two forces:
1. Weight of the block (W): The weight of the block is a downward force due to the gravitational pull. The weight is given as 120N.
2. Upward force exerted by the rope (N): The rope exerts an upward force on the block, which is mentioned as N in the question.
To find the net force, we can use the following formula:
Net force = Upward force - Weight
Substituting the given values:
Net force = N - 120N
Simplifying this equation, we get:
Net force = -119N
The negative sign indicates that the net force is acting in the opposite direction of the weight, which means it's acting upward. Therefore, the net force on the block is 119N upward.
