Explosions in Two Dimensions: a 1

Explosions in two dimensions: A 1.2-kg spring-activated toy bomb slides on a smooth surface along the x-axis with a speed of 0.50 m/s. At the origin 0, the bomb explodes into two fragments. Fragment 1 has a mass of 0.40 kg and a speed of 0.90 m/s along the negative y-axis. In the figure, the angle θ, made by the velocity vector of fragment 2 and the x-axis, is closest to

A) 31°.
B) 37°.
C) 38°.
D) 53°.
E) 59°.
