Just tried doing this same exact method with a problem from my physics text book and this method did not result in the correct answer that the book got...
So the acceleration of the 9kg and 4kg blocks are the same? ie the acceleration of the 4kg block is 4.75m/s and is positive since it is moving up the inclined plane if needed to be used to calculate internal forces such as Tension like you did with the 9kg block?
Hi I have the same problem, but the next question, the hanging block is submerged in water, calculate the new tension and acceleration? Please help. I’m not given the density or volume of the second block, only the mass. The block on the incline volume is 8cm^3.
in water the block weight would reduce slightly, ( the density of water is usually constant, around 1000kg/ m3) but u need to know the volume for the submerged block
mgsin(theta) in the direction parallel to the plane. This can be visualised by drawing a free body diagram. See this worked example th-cam.com/video/ZpL5BIUUmr0/w-d-xo.html
I'm sure that this is not relevant to the question you're answering, but I'm not sure how to even google my question without spending an inordinate amount of time sifting through information that doesn't directly address my question. My question is regarding the line perpendicular to the floor: Let's say I lean an object with a mass of x against a wall. A piece of plywood or whatever. It is leaning against the wall at an 85 degree angle relative to the floor, a 5 degree angle in terms of the triangle it creates at the point of contact with the wall. How much force is placed on the wall relative to mass x? I'm leaning a lot of boards against a wall and I need to know how much of a load that wall needs to be able to withstand.
Fuck why don't they teach it like this in school?
This is what I'm looking. Hope this help me
what will be the answer if mass intechange betwwen them, i mean heavy one keep in inclination, pls know me soon
These videos are soo underrated.... people please hit the like button!!

yes they’re the same because both are connected with unstretchable rope (both blocks act as one system)
Thank you so much!
Everyone's here because they're going to fail the physics test tomorrow
why you gotta call me out like that
@@beneng2626 nah literally 💀
anyone else watching this video an hour before the quiz?
Yes

wait....isnt the tension supposed to be considered?
No because it's an internal force in this problem
shouldn't it be mgcos theta instead of mgsin theta?
mgsin(theta) in the direction parallel to the plane. This can be visualised by drawing a free body diagram. See this worked example th-cam.com/video/ZpL5BIUUmr0/w-d-xo.html
what if the two masses were switched? how could we assume which direction the system would accelerate in?
intuitively the system would go in the direction of the heavier mass
it ussually follows the bigger mass bcs the friction wont mean too much

How’d it get 45.5? I’ve tried getting t by itself and I’ve gotten every answer but that one
YES, HOW?
why dont you use -9.8? you use +9.8.
my nigga
Wont The Acceleration be 13.74 m/sec^(2)
No.
