Bhumble: I've tried your method and set up the following equation for the sphere of smaller mass:
.5v(i)^2 - (100G/39) = .5v(f)^2 - (100G/25)
v(i) is v initial of smaller sphere and I used 0 for this value and solved for vf.
the mass of small sphere can be factored out and calcels in the...
I see. But the only way I can think of solving for v or distance, using the acceleration, would be to introduce the time variable(?)? but I don't see a way I can solve for specific times..? or am i just approaching the problem in a wrong way?
Physics Problem please help!
Homework Statement
An experiment is performed in deep space with two uniform spheres, one with mass 21.0 kg and the other with mass 100.0 kg. They have equal radii, = 0.40m . The spheres are released from rest with their centers a distance 39.0m apart. They...
