1.) (3B) A 10.2 kg weight hangs from a pulley as shown below, and an upward force on the rope (represented by the red arrow) raises the weight 8 cm (0.08 m). Image below by César Rincón.

B: What is the upward force in N represented by the red arrow? (Recall Session 3 HW #4, and Session 4 #3). red arrow is up and blue arrow is down with 100 N

2.) (3C) A 10.2 kg weight hangs from a pulley as shown below, and an upward force on the rope (represented by the red arrow) raises the weight 8 cm (0.08 m). Image below by César Rincón.

C: How far is the rope pulled upwards? RED ARROW IS UP AND BLUE ARROW IS DOWN WITH 100 N

3.) (3D) A 10.2 kg weight hangs from a pulley as shown below, and an upward force on the rope (represented by the red arrow) raises the weight 8 cm (0.08 m). Image below by César Rincón.

D: What is the work (in J) done by the upward force in lifting the block? RED ARROW IS UP AND BLUE ARROW IS DOWN WITH 100 N

4.) 3E) A 10.2 kg weight hangs from a pulley as shown below, and an upward force on the rope (represented by the red arrow) raises the weight 8 cm (0.08 m). Image below by César Rincón.

E: What is the mechanical advantage of the pulley? (Hint: Watch "Hewitt-Drew it! PHYSICS 33. Machines and Energy" video for a definition of Mechanical Energy and an analysis of pulleys and other simple machines, or see your textbook.) RED ARROW IS UP AND BLUE ARROW IS DOWN WITH 100 N
