Part 2:Egu al masses 19. Materials needed: String, 14 Washers (arandelas}, 2 Paperclips, 5 N Spring Scale (for measure mass. use the g (gram) scale) and a pulley. 2D. Thread a piece of string through the pulley so that you can attach washers to both ends of the string. The string should be long enough for one set of washers to touch the ground with the other set near the pulley. [Attach the washers using a paperclip or by tying them on]. 21. Use the spring scale to weigh the 2 set of ? washers that represent M2 5; M1. Record the mass of the 2 sets of ? washers in M1 a M2 below. Page 5 of 13 Newton's Laws Mass 1 (a set of 7 washers) in gram is: Mass 2 (a set of 7 washers) in gram is: 22. Attach the sets of seven washers to each end of the string. This means having the same mass on each side. 23. Insert below a photo of your experimental setup for part 2, step 22. Post-Lab Analysis Guide Questions. You must use these guide question to write your analyses paragraph (s). 24. Define Friction force (for credit include the reference). 25. Observe and answer below, how the washers behave in the pulley having the same mass in each side (7 washers in 1 side and 7 in the other side)? 25a. Which two Newton Laws (1st,2nd, or 3d) applies to this scenario (select 2)? Newton's first law of motion applies to this scenario. Newton's second law of motion applies to this scenario. Newton's third law of motion applies to this scenario. 25b. Observe and comment below, what do you observe about the motion of the washers when you give one set a downward push? Does it stop before it reaches the floor? 25c. What interpretation can be made about your observations based on Newton's laws
