$6$ B$).$ A $1\mathrm{.}2-kg$ spring$-$activated toy bomb slides on a smooth surface along the x $-$axis with a speed of $0\mathrm{.}50\frac{m}{s}.$ At the origin $0,$ the bomb explodes into two fragments. Fragment $1$ has a mass of $0\mathrm{.}40$ kg and a speed of $0\mathrm{.}90\frac{m}{s}$ along the negative $y-$axis. The velocity vector of fragment $2$ makes an angle $$ with the positive x $-$axis as shown in Figure $4.$ What are the magnitude and direction of the velocity vector of fragment $2?$
