A PHYS 1510 student was working on a robotics project. The joints on the machine they were building were powered by pistons. Based on how hot the machine was getting, the student was able to figure out that 2.34 J of thermal energy was produced by every piston every time the piston was fully extended to 0.4064 m. What was the force of friction that the piston experienced during every extension? Assume friction is the only source of thermal energy. Include units in Sl.

5. This time, the pendulum is 1.55 m long and has a mass of 3.07 kg. You give it a push away from vertical so that it starts swinging with a speed of 2.65 m/s. Due to friction at the pivot point, 1.00 Joule of the pendulum s initial kinetic energy is lost as heat during the upward swing. What maximum angle will it reach, with respect to the vertical, before falling back down? 44.4 degrees 37.8 degrees 39.7 degrees 49.1 degrees
