Question

A worker drags a crate across the factory floor with 25 N west pulling on a rope tied to the crate horizontally. A 13 N frictional force is making it more difficult. Identify all forces and find the net force.

Answer 1

The net force exerted on the crate is 12 N directed west, calculated by subtracting the 13 N frictional force from the 25 N pulling force.

Step-by-step explanation:

The question pertains to the topic of forces and motions, specifically regarding the calculation of net force. When a worker drags a crate across the factory floor with 25 N west pulling on a rope tied to the crate horizontally, and there is a 13 N frictional force opposing the motion, we can find the net force applied to the crate. To calculate the net force, we subtract the frictional force from the applied force, because they act in opposite directions. Thus, the net force exerted westward on the crate is:

Net force = Applied force - Frictional force = 25 N - 13 N = 12 N directed west.
