i$.0,50$ms A billiard ball, labeled $1,$ moving horizontally strikes another billiard ball, labeled $2,$ at rest. Before impact, ball $1$ was moving at a speed of $\backslash (2\mathrm{.}1\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ),$ and after impact it is moving at $\backslash (0\mathrm{.}51\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash )$ at $\backslash (54^\{\backslash$circ$\}\backslash )$ from the original direction.

If the two balls have equal masses of $307$ g $,$ what is the velocity of the ball $2$ after the impact?

For the direction, measure it relative to the initial direction of the of ball $1.$ Your angle should be positive if it is towards ball $1$ and negative if it is away from ball $1.$
