- 1. How much work was done by a machine that exerts a 5000 N force to compress a 10-meter-long steel bar so it becomes 3 meters in length. 2. Find the angle between the 500 N applied force and the 3-meter displacement if the work done is 1500 Joules. Hiii please write a solution thank youQuestion 1 The first question does not require the coefficient of friction. Doesn't all the work being performed by the system = friction? Friction is the only thing that is performing work?ACTIVITY 4: DECODE THE MESSAGE Directions: Determine the work done by the force on a given system in the following problems.
