A large wooden crate is pushed up an inclined plane by a worker. The inclined plane has a rough surface. Three forces act on the crate: gravitational force, the applied force from the worker, and the frictional force. Which of the following correctly identifies the signs on the work done by these three forces as the crate moves up the ramp at a constant speed? A. The applied force => positive work, gravity => positive work, friction => negative work B. The applied force => negative work, gravity => positive work, friction => negative work C. The applied force => positive work, gravity => negative work, friction => negative work D. The applied force => positive work, gravity => negative work, friction => positive work

- 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?

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
