Homework Statement A strait fin fabricated from 2024 AL with k=185w/mK base thickness=3mm, length=15mm. Tb=100C and fluid temp is Tinfinity=20C and h =50 w/m^2K. For the foregoing conditions and a fin of unit width, compare the fin heat rate, efficiency, and volume of a triangular fin...

What answer are you getting?

Okay so I tried using the conservation of energy Ue=Ke and then broke it down to mgh=(mv^2)/2 and then simplified to find velocity but this is where I am confused. I tried using V=(2gh)^1/2 and it was wrong. Then I tried to find the component of gravity at a 30 degree angle with respect to y...

So by using Ue=Uk and breaking it down I can figure out the answer!? That is so beautifully simply! Thank you

This question, I have absolutely no idea what to do. Question: Tarzan, in one tree, sights Jane in another tree. He grabs the end of a vine with length 20 m that makes an angle of 45 degrees with the vertical, steps off his tree limb, and swings down and then up to Jane's open arms. When...
