- A brick of a certain metal has area on top of 3.74 cm x 10.78 cm. It has mass 1,162 g. How high is the brick in cm? The metal has density of 16.6 g/cm3 2.54 cm = 1 inch l x h x w = V V = m/d1. 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.
