Fnet = ma, x = xo + Voxt += axt², Vx = Vox + axt, (v₂)² = (vox)² + 2axAx, g = 9.8 m/sec² Problem 1: The three ropes in the Figure are tied to a small, very light ring. Two of the ropes are anchored to walls at right angles, and the third rope pulls as shown. a) What is T₁, the tension from Rope 1 for the Figure below on the left? Answer: 86.6 N b) What is T₂, the tension from Rope 2 for the Figure below on the left? Answer: 50.0 N c) What is T3x, the x-component of the tension from Rope 3 for the Figure below on the right? Answer: 50 N. d) What is T3y, the y-component of the tension from Rope 3 for the Figure below on the right? Answer: 80 N. e) What is T3, the tension from Rope 3 for the Figure below on the right? Answer: T3 = √(T3x)² + (T3y)² = 94.3 N Rope 1 Rope 2 √30° 100 N 0.60 m 0.80 m T₁ = 50 N T₂ = 80 N T₁ w 34
