Are the masses on top of each other, or just side by side with one pushing the other along? Is that mentioned in the question? That will affect the answer to b). If it is one on top of each other, have a look at my previous post.harhar said:Ok the EXACT question is the same concept but w/ different numbers cuz I just tried to use easy numbers to deal with..
2 masses in contact w/ eachother are 0.113kg and 0.139kg. No friction. The applied horiz. force of magnitude 5.38x10^-2 N is exerted on the heavier mass.
Determine:
a)magnitude of accel. of the 2 mass system.
b)magnitude of the force exerted by each of the 2 masses on the other
I've already gotten a) which is 0.213m/s^2
I'm pretty sure there can be friction between the two masses.chroot said:I assume there's a picture, also, showing one mass above the other. You need to tell us about those parts of the question when posting your question here, or we won't be able to make sense of it.
The answer to b) is simply the weight of the mass on top. The top mass presses its weight down on the bottom mass, and the bottom mass in turn pushes back up, supporting it.
