"For a two-body collision involving objects with different masses, a frame of reference which has the same velocity relative to the laboratory as does the center of mass of the two objects is:"
" A. a frame for which the momentum of the incident object is zero B. a frame for which the momentum of the target object is zero C. a frame for wh...
Whenever an object strikes a stationary object of equal mass:
" A. the two objects cannot stick together B. the collision must be elastic C. thefirst object must stop D. momentum is not necessarily conserved ...
"A 640-N acrobat falls 5.0m from rest into a net. The net tosses him back up with the same speed he had just before he hit the net. The magnitude of the average upward force exerted on him by the net during this collision is:"
" A. 32N B. 64N C. 320N D. 640N E. impossible to determine from given data"
