Well, I'm getting answers where the force of friction is greater than kx meaning the blocks won't be able to go anywhere. Thanks a bunch for all the help, I think I've got it all now.

When I do that I obtain the same answers I got in the post above, so I assume they were right. And for part c I get answers that suggest both blocks aren't moved when the coefficient of friction is that strong.

So it will be net force divided by the mass to get acceleration First block: -(kx - umg)/m = a = [(-3.85N/m)(0.08m)+(0.100)(0.250kg)(9.81m/s2)]/0.250kg = -.0251m/s2 Second block [(-3.85N/m)(0.08m)-(0.100(0.250kg)(9.81m/s2)]/0.500kg = a negative number indicating that the friction force is...

When I do that I get the same numbers as above and that doesn't make sense, especially with friction because the larger block has a higher acceleration, could you possibly try out your way with the numbers so I can see if I actually understand what you're saying?

So this would be the correct answer for the first part then? Since Fx = -kx and F = ma then ma=-kx and -kx/m = a So for the first block (-3.85N/m)(0.08m)/(0.250kg) = -1.232 m/s2 And for the second block (-3.85N/m)(-0.08m)/(0.500kg) = 0.616 m/s2 I had actually calculated both of the...

Homework Statement A light spring with force constant 3.85 N/m is compressed by 8.00 cm as it is held between a 0.250-kg block on the left and a 0.500-kg block on the right, both resting on a horizontal surface. The spring exerts a force on each block, tending to push them apart. The blocks...

Yeah, the astericks are actually a dot, so it may have something to do with the dot product where it's AxBx + AyBy or something along those lines.

Homework Statement Let B = 5.00m at 60 degrees. Let C have the same magnitude as A and a direction angle greater than that of A by 25.0 degrees. Let A*B = 30.0 m^2 and B*C = 35.0 m2. Find A. Homework Equations Pythagoras maybe. The Attempt at a Solution Well, if A*B is 30 m^2, and...
