Problem

Two hover pucks glide towards each other, collide and then glide away. Puck A $(5\mathrm{.}0kg)$ was initially travelling at $2\mathrm{.}0\frac{m}{s}[$E $[$:$25N\}.$ Puck B $(3\mathrm{.}0kg)$ was initially travelling at $4\mathrm{.}0\frac{m}{s}[$E $[$:$30S\}.$ After the collision, puck A travelled at $1\mathrm{.}6\frac{m}{s}[E27S].$ Determine the velocity of Puck $B$ after the collision.
