Question and answer
A 0.100-kilogram white ball moving with a velocity of 5 meters/second along the positive x-axis hits a stationary blue ball of the same mass. Energy is not necessarily conserved, but momentum is. After the collision, the white ball moves off at an angle of 20° with respect to the positive x-axis and at a velocity 3.5 meters/second. The blue ball moves at an angle of -35° and a velocity of 2.1 meters/second. What is the final y-momentum of the system?
If momentum is conserved the final y-momentum of the system should be ZERO. To check that it is zero, see if 3.5 sin (20 deg) = 2.1 sin (35 deg) [ I didn't put in the masses since they are equal ] I get 1.197 = 1.205
