Hell yeah! Thanks for the advices! Yes right now I am having a extensive research on the field of mechanical engineering, the things they usually do, etc... @ Danger, yes you make sense... Just a follow up question, I want to know the PROS and CONS of being a mechanical engineer or taking up...

Hi! I'm currently a 2nd Year Civil engineering student, and I wrote this topic for I am seeking a professional advice, actually I have doubts whether should I stay in my current course or to shift in mechanical engineering, and lately I find my course a bit boring and uninteresting (is...

Yeah your right! thank you! By the way there was a follow up question on that... Homework Statement If the power required to accelerate the air is 40% of the answer from the last problem due to the professor's sleek aerodynamic shape, a) what is the power required to accelerate the...

yeah I got it! Thank you very much!... I didn't know It was that easy, I wasted a week trying to solve this tricky problem...

thats 2610 Hp or 1 947 060 Nm and substitute to energy... I ve tried that, and still got the wrong answer, my hunch is that we should utilize the given ( the 427 cu in engine) but tried it an still got the wrong answer... btw the answer on that one is 54 mph...

Homework Statement A physics professor bicycles through air at a speed of v= 36 km/hr. The density of Air is 1.29 kg per m^3. the professor has a cross section of 0.5 m^2. assume all of the air the professor swept out is accelerated to v. a.) What is the mass of the air swept out by the...

Ive tried that.. but since the 427 in cu engine contains fuel to run the car, i assumed that this chemical energy will transform to kinetic energy when moving (since burning 1 L of gasoline is equal to 3.5 x10^7 j/s , so I substituted it in the formula, and still got a wrong answer... does my...

Homework Statement A 1967 Corvette has a weight of 3020 lbs. The 427 cu-in engine was rated at 435 hp at 5400 rpm. a) If the engine used all 435 hp at 100% efficiency during acceleration, what speed would the car attain after 6 seconds? b) What is the average acceleration? (in “g”s)...

Homework Statement Two blocks, A and B (mA=50 kg and mB=100 kg), are connected by a string as shown. If the blocks begin at rest, what will their speeds be after A has slid a distance d = 0.25 m? Assume the pulley and incline are frictionless. Homework Equations K= .5mv^2 P=mgh...
