1. 15° T₁ W T₂ J.10° Our goal is to calculate the tensions in the two ropes if the person is momentarily motionless (Part 3). Set up Newton's 2nd Law in the x and y directions when the system is at rest. What should the sum of the forces add up to? 1. Set-up Newton's 2nd Law is in terms of symbols and notations only. Please do not substitute any numerical values except for the angles. Write expressions for ΣF, and ΣF, in terms of T₁, T₂, m, g, and the numerical values of the angles. For example, you may express the x-component of T₁ as — T₁sin(15°) or T₁cos(105⁰) 1 2. Take the upward direction to be the +y-direction, and to the right to be the +x-direction.
The diagram shows two force vectors. Which statement best describes the vectors? O The magnitudes of the force vectors are the same. O The net force of these vectors will be unbalanced. The vectors are pulling in opposite directions. O The force vectors will represent balanced forces.
