Pen colors make the step-by-step options clear. Red is supplied to highlight algebra procedures, and also to substitute numeric values in the last step of a solution. When a solution switches to a new train of thought a various pen color emphasizes the switch, so that remedies are exceptionally methodical and also arranged. Solutions are classroom tested, and also produced by an competent physics teacher. Videos are delivered via a high performance content distribution netoccupational. No waiting for videos to pack or buffer. Pausage, rewind, repeat, and never miss out on what is being sassist.

g"s and we"ll convert that into meters per second squared. So, we have actually 9.8 meters per second squared per g; the g"s cancel offering us 58.8 meters per second squared. We know that centripetal acceleration is v squared over r and also we"ll solve this for r to find out what radius of curvature this course need to have so that the acceleration is 6g"s. So, we"ll times by r over a c and also the a c cancels on the left and the r cancels on the ideal leaving us with r amounts to v squared over centripetal acceleration. So that"s 233.33 meters per second squared separated by 58.8 meters per second squared offers us about 930 meters is the radius of this loop. And then for part B, we usage that free-body diagram to talk around the lift force upwards minus gravity downwards has to equal ma, that"s gonna be the net pressure and a is centripetal acceleration which we have already calculated is 58.8 meters per second squared. So, the lift force is the apparent weight of the pilot; it"s the normal pressure that they endure being pushed up by the seat and we"ll include F g both sides below to settle for the lift pressure. And lift pressure is m times acceleration plus gravity so that"s ma c plus mg and also you have the right to element out the m"s and you acquire 78 kilograms times 58.8 meters per second squared plus 9.8 meters per second squared and let"s figure out what that provides. 78 times 58.8 plus 9.8 renders about 5400 with two substantial figures. That"s the apparent weight at the bottom of the loop. At the optimal of the loop, the pilot will certainly will certainly have gravity downwards and also then it"s type of a misnomer, it"s kind of confmaking use of to call this a lift pressure bereason it"s actually gonna be a force that"s pushing dvery own in the direction of the ground to keep the aircraft going downwards in this loop. So, it goes dvery own along this path yet I"ll simply save calling it a lift force; it"s the pressure you know that the wings are, you know, the air is pushing on the wings and also then the wings push the plane dvery own via this force. OK So they are both pointing in the exact same direction in the direction of acceleration and also so we will speak to the radial direction towards the facility positive. So that renders gravity positive and also the lift force positive equates to mass times acceleration; acceleration is v squared over r because we deserve to watch the acceleration is in a circle… it"s radial so it"s v squared over r and substituting for gravity is mg. And then we fix for this lift pressure and also we"ll subtract mg from both sides here and also we gain lift force is mv squared over r minus mg; variable out the m and you get m times v squared over r. 78 kilograms times 233.33 squared over 925.9 and also then minus 9.8 and also we gain about 3800 newtons is the effective weight at the height of the loop.">

Dear Mr. Dychko,Physics has actually never been my solid allude so I was nervous around taking Physics this semester. I am so glad that I uncovered your website! I am frequently puzzled during my classes bereason my teacher goes so conveniently over the material and often tends to be disarranged. Doing the book problems along with watching your solution videos has aided me understand the material a lot much better. You have also showed me a few tricks that I"ve been able to effectively usage throughout my exams. Thank you for making this site!

I wanted to say thanks to you for taking the time and also initiative of functioning out the solutions! I recognize that was a tedious task, however those of us that essential that added assistance GREATLY appreciate it!! I would certainly not have been able to have actually done and I did in Physics II without the breakdvery own step by action clarification that was offered. Thanks aget for your effort! I would certainly highly recommend the usage of this site to anyone taking Physics.

These videos are 40 times more practical than lecture, the message book, and so much cheeper and effective than a private tutor.

Thank you so a lot... the videos were very advantageous. I was researching at McGill in a class of 650 students so it was very beneficial to be able to go over any kind of inquiries I was unsure of. And your explanations were good. 5 out of 5 star rating from me.

Thank you so much for making all these videos, you helped me gain an A in both my college physics courses! With your help I finished up functioning simply about every problem in the Giancoli book. Not just did I gain the great qualities but these exercises have prcooktop inuseful to expertise and functioning even more facility difficulties in the advanced classes for my significant in Mechanical Engineering.
