The spring has a stiffness k 50 lb/ft and an unstretched length of 2 ft. As shown, it is confined by the plate and wall using cables so that its length is 1.5 ft. A 4.4-lb block is given a speed u when it is at A, and it slides down the incline having a coefficient of kinetic friction = 0.2. It strikes the plate and pushes it forward 0.25 ft before stopping. Neglect the mass of the plate and spring (Elgure 1).

What is the answer
- Figure above shows the cross section of a wall made of two layers. The thickness of the 2 nd layer is L2= 0.70L1. The thermal conductivities of the layers are 0.25 and 0.75 W/mK, respectively and thermal conduction is steady. If the temperatures at inlet and between the layers are Ti = 30.0°C and T=8 °C, respectively; what is the outside temperature To for unit area?
