While I do agree with you, are you aware you left this comment on a video which has average fewer than 5 views per day? I love this video. There is so much good learning to be had here.

I had a question, so 9:46, the height of the dart final is to the tip but the height of the cardboard final is of the center of mass. So wouldn't that mean that the height of the dart final would also have to be the center of mass of the dart?

Hello Mr.P! I really enjoyed your video!! However, I'm not sure if I'm making a mistake, but I'm getting a slightly different answer of 47,37°. I've also tried to calculate the angle with both of your final formulas, but I still get the same answer :( I don't know what I'm doing wrong.

Will you ever cover other topics like thermodynamics, statistical mechanics, quantum mechanics etc the typical undergraduate stuff? A lot of your videos are classical mechanics at the moment.

Eventually, yes. Currently I am working though the AP Physics 1 curriculum and none of those topics are included.

Hello Mr. P, I solved the problem in an another way and got an angle of 46.2 degrees, could you please check my solutuion and tell me if it is correct? The different thing I did was in the conservation of mechanical energy equation, instead of writing an expression for both potential energies of the board and dart, I wrote one expression for both and got the height from the center of mass of the system which was 0.12817 meters. (m + M)gh = 0.5(Inertia of system)(w)² h = 0.1287 m I then calculated the position of the center of mass which turned out to be 0.1775 meters from the AOR. Using this information I then used sine inverse where the distance the center of mass of the system from the pivot was the hypotenuse and the height of the system was the opposite and got an angle of 46.2 degrees. Thanks in advance 😊

can part 2 be solved by using the torque from gravity to find angular acceleration then using angular kinematics?
@FlippingPhysics

The torque caused by the force of gravity is not constant, that means the angular acceleration is not constant. So, no, it cannot be solved that way.

@@FlippingPhysicsI took some time to try to solve it with kinematics, since angular acceleration is dependent on cos[theta] we can use the integral form of wf^2 = wi^2 + 2a(change in theta) And integrate it from 0 to max theta (when wf = 0) and we’d get the same expression. Ps. Love your vids, saved me in both AP physics E&M and Mechanics so I appreciate it, keep up the good work!

I laughed so hard at your long explanation video(which was damn funny)! but you 4.5% of error comes from miscalculation of air resistance against the cardboard rising 😅. Just to let you know, I'm a normal human btw. not a computer brain like you😅😊
