Chapter 17.4, Problem 3bTH

On the same horizontal surface, object C collides with an initially stationary target, object Z. The initial speeds of objects C and A are the same, and $m_X=m_Z>m_A=m_C$ .

After the collisions, object C moves in the direction shown and has the same final speed as object A.

i. In the space below, copy the vectors ${\stackrel{\to }{\upsilon }}_{c_{\text{i}}}$ and ${\stackrel{\to }{\upsilon }}_{c_{\text{f}}}$ with their tails together. Use these vectors to draw the change in velocity vector $△\stackrel{\to }{\upsilon }$ for glider C.
ii. Is the magnitude of the change in velocity vector of object Agreater than, less than, or equal to the magnitude of the change in velocity vector of object C? Explain.
iii. Is the magnitude of the change in momentum vector of object Agreater than, less than, or equal to the magnitude of the change in momentum vector of object C? Explain.
iv. Is the final speed of object X greater than, less than, or equal to the final speed of object Z? Explain.
