Problem $4$

A $5\mathrm{.}50-kg$ bowling ball moving at $9\mathrm{.}00\frac{m}{s}$ collides with a $0\mathrm{.}850-kg$ bowling pin, which is scattered at an angle of $85\mathrm{.}0$ to the initial direction of the bowling ball and with a speed of $15\mathrm{.}0\frac{m}{s}.$

A$.$ Calculate the final velocity $($magnitude and direction$)$ of the bowling ball.

$[6$ points$]$

B$.$ From your solution in part $A,$ explain the type of collision in this system.
