A small piece of space junk of mass 8.6 kg is initially moving toward the satellite with velocity (-2200, 0, o) m/s. The space junk hits the edge of the satellite as shown in the figure below, and moves off with a new velocity -1300, 480, 0) m/s. Both before and after the collision, the rotation of the space junk is negligible.

Additional Materials Section 11.7 Submit Answer Save ProgressExplanation / Answer
Initial agular momentum = MR^2/2 *2-mv2 = 245*6.3^2/2*2 - 8.6*2200 = -9195
so final angular meomentum must alo be same so
MR^2/2*w -mvx = -9195
245*6.3^2/2*w-8.6*1300 = -9195
gives w = 0.408 rad/s (clockwise)
c) rise in energy = 0 since there is no other forces involved and so the energy always stays inthe system
