A steel ball of mass 60 grams, moving at 80 cm / sec, collides with a stationary marble of mass 20 grams. As a result of the collision the steel ball slows to 50 cm / sec and the marble speeds up to 70 cm / sec.
• Is the total momentum of the system after collision the same as the total momentum before?
answer/question/discussion:
The momentum wasn’t conserved because the momentum before was .0048 kgm/s and after it was .0044 kgm/s
• What would the marble velocity have to be in order to exactly conserve momentum?
answer/question/discussion:
Using the conservation of momentum formula the marble needs to speed up to 90cm/s
