Homework Statement Two spheres have equal radius R = 14m and mass m = 1420kg. Their centers are separated a distance 4R. The spheres are released from rest. What will be their speed when they collide? Answer in m/s. Homework Equations U(g) = -G*m1*m2/R The Attempt at a Solution We...

Thanks a ton, Doc Al! I finally got the answer right lol.

(1) Yeah, that makes a lot more sense. (2) I figured there was no related between the acceleration of the two cords since they were not on the same pulley. Are they equal but opposite (a1 = -a2)? (3) I actually meant to fill that in. Following from friction force = u x n, Ffriction =...

Homework Statement I attached a picture of the given figure to this thread. The suspended 2.5kg mass is moving up, the 2.9kg mass on the ramp is sliding down, and the 9kg mass is moving down. It is given that there is friction between the block on the ramp and the ramp itself with a coefficient...

Thanks a lot man. I messed with it for a minute and figured it out.

Homework Statement A block with mass 7.01kg rests on a frictionless table. The mass is connected by a cord, passing over a pulley to another block with mass 2.35kg that hangs in the air. Assume the cord to be massless and unstretchable and the pulley to have no friction or rotational inertia...
