a1=F/m1? I don't understand how ap and a1 are related... Could you hint something please?

How do I find a1? Or do I just leave it as is? Thanks for putting up with me so far...

Which other two equations? I am back to being confused... :( I tried 2T=-mp *ap+F but I just over complicated things... and I don't think I was on the right track. I also know that T=T1=T2=m1*a1=m2*a2, but that doesn't help much...

Wait... i feel stupid now... I just sort of worked it out and (F-2T)/mp= ap. I had F=mp*ap+2T written the entire time, but it didn't dawn upon me to try and solve for ap. Is my thinking correct? If so, how do I solve for T?

Actually.. that was a stupid statement. If there is tension in the rope, the acceleration of the mass being dragged has to be less than the acceleration of the pulley. I don't understand how to find the acceleration of the mass being dragged though.

So... acceleration of the individual masses= F/m1? But I can't see how that could be if the acceleration of the pulley is dragging the blocks at the same acceleration as the pulley, due to the string being attached to the blocks.

So umm.. how do I find the tension in the rope? Does the force exerted on the pulley have a effect on the tension in the rope?

Then you would get ap=F/(mp+2m)... which is essentially the same thing because T=2(ap)m. I am so confused, sorry about this.

Tension in the top rope = m1*ap = T1 Tension in the bottom rope = m2*ap = T2 F= mp*ap + T1 + T2 This is what I got so far... is that correct? If so then... F= ap(m1+m2+mp)... and the only given hint in the problem states that ap =/= F/(m1+m2+mp)

Would you add the forces together? And I don't think the lengths of the string in this problem actually matter. I also don't understand why the length of the two strings are 0. Also, how can I figure out the acceleration of the two blocks if I don't know the acceleration of the pulley? Would...

Homework Statement A curve with a 200-m radius on a level road is banked at the correct angle for a speed of 60 km/h, i.e. a car traveling at this speed would remain on the road, even if the surface were frictionless. a) If a car travels around this curve at a speed of 90 km/h, what is the...

Homework Statement Two blocks of mass m1 and m2, resting on a frictionless tabletop, are connected by a massless string passing through a frictionless pulley of mass mp. The figure shows a top view of the arrangement. If a force of magnitude F is applied to the pulley in the direction...
