Answer
Here's how to calculate the positive work done:1. **Identify the force doing positive work:** The 100 N applied force is doing positive work because it's in the same direction as the crate's displacement. The friction force does negative work.2. **Calculate the work done by the applied force:** Work is defined as force multiplied by displacement (in the direction of the force). So, the work done by the applied force is: Work = Force x Displacement Work = 100 N x 25 m Work = 2500 JoulesTherefore, the positive amount of work done is
Joules.
