Hi all, help!!! I am looking for an equation that gives the relationship between the initial and final velocities of a frictionless elastic collision. This equation must work for when the velocity of the second object IS NOT equal to zero, as well as when it is. Thank you!!

Question

mrdoe · Answer

Use energy conservation (hint KE is conserved)

anonymous · Answer

Yes. momentum is conserved [sum of m v values]
Kinetic energy is conserved [ sum of (1/2) m v^2 values.
