You go to slide your chair out from under the table at Thanksgiving at your grandma's house. She hasn't
updated the terrible mint-colored carpet in her dining room in the last 40 years. The combined mass of
you and your chair is 62.0 kg and the coefficient of static friction between the chair legs and the carpet is
0.71. You push backwards with your feet using a force of 350 N. Imagine this force to be horizontal.
What is your acceleration during this 350 N push?
b. Why is it always easier to slide out if you try to stand up while you do it? No math, just logic.
What effective mass do you and the chair need to have in order to allow the 350 N push to start
the chair moving?

60. Go The drawing shows a circus clown who weighs
890 N. The coefficient of static friction between the
clown's feet and the ground is 0.53. He pulls verti-
cally downward on a rope that passes around three
pulleys and is tied around his feet. What is the mini-
mum pulling force that the clown must exert to yank
his feet out from under himself?
Only two horizontal forces act on a 4.3 kg body. One force is 6.9 N, acting due east, and the other is 2.2 N, acting 28° north of west. What is the magnitude of the body's acceleration?
