Fv = 390 N Sur Previous Answers Mountaineers often use a rope to lower themselves down the face of a cliff (this is called rappelling). They do this with their body nearly horizontal and their feet pushing against the cliff (Eigure 1). Suppose that an 78.6-kg climber, who is 1.88 m tall and has a center of gravity 1.0 m from his feet, rappels down a vertical cliff with his body raised 40.4° above the horizontal. He holds the rope 1.54 m from his feet, and it makes a 20.7° angle with the cliff face. ✓ Correct Part D Figure 1 of 1 What minimum coefficient of static friction is needed to prevent the climber's feet from slipping on the cliff face if he has one foot at a time against the cliff?

Tires are one of the most frequently encountered applications of the gas laws that we never think about. We fill our tires with air, or with nitrogen, but it always works out the same way. Enough gas goes in, the tire inflates, and then the pressure starts going up. In this assignment, we’ll be investigating the ways that the gas laws impact how we treat our tires. Q1. I have good information that in Fast 29, Dominic Toretto (Vin Diesel) will need to refill a tire quickly during a dramatic moment. For this reason, he has a 3.00 L tank of compressed air that is under 2.7892*103 mmHg and is kept cool in dry ice at -35.0 °C. When Dom hooks his compressed air up to his completely empty 10.50 L tire at 39.2 °C and lets it run, what will his final tire pressure be, in atm? Assume all the air is transferred into the tire. Is his tire pressure above the 2.31 atm that he needs to save the planet/his family/his crew? Q2. Your car tire pressure sensor looks to see when your tire pressure…

Learning Goal: To be able to add and subtract vectors using geometric and vector addition. A brother and sister are playing in the woods, when suddenly the brother realizes that they are separated. The last place he remembers seeing his sister is at a particularly large tree. The brother traveled d₁ = 21.0 m at 0₁ = 26.0° from the tree then turned and traveled 4 = d2 11.0 m at 02 = 140°. Meanwhile, the sister traveled d3 = 17.5 m at an angle of 03-117° from the tree. The angles are given with respect to east with counterclockwise being defined as positive(Figure 1) Figure d3 03 d₂ 0₁ 0₂ d₁ 1 of 4 X > v Confect Part C Distance to home - After the boy has found his sister, they want to travel the shortest path home.
