Yоu must type yоur аnswer intо the given box аnd show аll your work. For credit, please follow the instructions below and show all the steps. Step 1. Type the provided values along with their units in the problem, and designate a specific symbol (standard) for each known value and value that you need to determine. Step 2. Type the general equations that you will use to solve the problem using the variables (no numbers yet). Step 3. Show steps to utilize the provided values and their respective units to calculate the answer for the value you need to determine. A uniform plank, weighing 200 N, is supported by two ropes at its ends. A worker weighing 600 N stands 2 meters from the left end, and another worker weighing 450 N stands 3 meters from the right end. The plank is 6 meters long. If the tension in the left rope is 800 N, what is the tension in the right rope? (Assume the plank's weight acts at its center.)

A window cleaner with a mass of 70 kg slides down a vertical safety rope with an acceleration of 2.0 m/s2. What is the magnitude of the friction force exerted by the rope on the cleaner? (Assume the acceleration due to gravity is 9.8 m/s2.)
