Spheres A (mass 0.020 kg), B (mass 0.030 kg), and C (mass
0.050 kg) are approaching the origin as they slide on a frictionless air
table. The initial velocities of A and B are given in Fig. P8.69. All three
spheres arrive at the origin at the same time and stick together. (a) What
must the x- and y-components of the initial velocity of C be if all three
objects are to end up moving at 0.50 m/s in the +x-direction after the col-
lision? (b) If C has the velocity found in part (a), what is the change in the
kinetic energy of the system of three spheres as a result of the collision?

Either as the result of the forces on current carrying wires, or as a magnetic dipole moment trying to line up with an external field (e.g. like a compass). Note: the magnetic moment of a coil points in the direction of the coil's magnetic field at the center of the coil. d) Forces: We can consider the left-most piece of the loop (labeled ○) as a short segment of straight wire carrying current directly out of the page at us. Similarly, we can consider the right-most piece of the loop (labeled ) as a short segment straight wire carrying current directly into the page, away from us. Add to the picture below the two forces due to the external magnetic field acting on these two segments. Then describe how these two forces give a torque and determine if the torque acts to rotate the loop clockwise or counterclockwise according to this picture?
