An object of mass m has an initial velocity of u at point A, where it enters the fixed incline shown below. The kinetic friction coefficient between the object and the surface is μ 0.3. An instant after the object passes point B the normal reaction force from the supporting surface onto the object drops to one-half the value it had before reaching B. The distance d=4mm. Determine: a) the acceleration of the object just before reaching point B, b) the initial velocity u of the object at A.

Part 1: Do the Analysis of the Ocean Thermal Gradient Power Plant shown below. Your Analysis will be easier to do in EES but it is up to you. Your EES program must be well documented and documentation in your code should reference system sketches. (The cycle and individual components) These sketches are done on attached engineering or typing paper, unless you are able to draw them in EES. You must validate your results with hand calculations on engineering paper that invoke the 1 and 2 Law from the perspective of the entire cycle, not the individual components. Of course, a system sketch is required. nd 1. An ocean thermal gradient power plant using a simple non-ideal Rankine Cycle operates with a peak boiler temperature of 70 °F and a condenser temperature of 40 °F. The warm surface water of the ocean is supplying the thermal energy to the boiler. Assume a high source temperature of 80 °F. The cooler water deeper in the ocean is the sink for heat rejection at the condenser. Assume a…

4. Storage batteries (Li ion, solid polymer electrolyte) that have small volumes and masses and high energy storage densities are in demand for both electric and hybrid vehicle applications. Estimate the smallest weight battery that could be used to provide full vehicle power for one hour of urban commuting in a family-sized five-passenger sedan. And, do some research to determine if the range (energy and mass) you calculated is realistic. Explain why or why not in 2-3 sentences. You can assume: The minimum power levels for such vehicles are 20 hp at average speeds, and the maximum power levels are 40 hp at peak acceleration. One hour of driving = 40 hp for 15 minutes + 20 hp for 45 minutes Li ion solid polymer electrolyte batteries have a specific energy density of 1400 kJ/kg

I will rate you with “LIKE/UPVOTE," if it is COMPLETE STEP-BY-STEP SOLUTION.   If it is INCOMPLETE SOLUTION and there are SHORTCUTS OF SOLUTION, I will rate you with “DISLIKE/DOWNVOTE.”    Topics we discussed:  Statics of Rigid Bodies, Force System of a Force, Moment of a Force, Moment of a Force-Scalar Formulation, Moment of a Force-Vector Formulation, and Principle of Moment, Simplification of a Force System and Couple System, Reduction of Simple Distributed Load
