Four Wires form corners of a square. Force exerted by 3 of them on 1. Concept help!
Homework Statement
side length "a"= 5.5 cm
current through wires "I" = 1.6A
"L" of lower right wire= 1 cm
upper and lower left currents are out of the page
upper and lower right currents are into the...
When it's accelerating up? Because sense of weight comes from Normal Force and the normal force is greater in a lift accelerating up. But I still don't get how this gives mass 2 a more negative accel?
When you're going up, if you feel heavier, mass 2 would be heavier as well. But wouldn't the...
Homework Statement
A simple Atwood machine composed of a single pulley and two masses, m1 and m2 is on an elevator. When m1= 44.7kg and m2=45.3kg, it takes 5.00s for mass m2 to descend exactly one meter from rest relative to the elevator. What is the elevator's motion? (That is, is it moving...
Homework Statement
A 0.840- kg glider on a level air track is joined by strings to two hanging masses. As seen in the figure, the mass on the left is 4.85 kg and the one on the right is 3.62 kg The strings have negligible mass and pass over light, frictionless pulleys. Find the acceleration of...
[PLAIN]http://dl.dropbox.com/u/14756133/physics%20two%20clay%20pots.pngSorry. I accidentally typed plus. If you look at the following equation, though, I have it as a minus. I'm subtracting the force due to gravity from the force due to tension in the downward motion of mass 3. and my positive...
Homework Statement
Two clay pots (m1 = 6 kg, m2 = 3 kg) joined together by a light string rest on a table. The frictional coefficient between the pots and the table is 0.35. The pots are also joined to a suspended mass (m3 = 4kg) by a string of negligible mass passed over an ideal pulley as...
