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 0, made by the velocity vector of fragment 2 and the X-axis, is closest to 0.80 kg 0.50 m/s 1.2kg Before After 040 kg 0.90 m/s . Answer:
A) 319
B) 370 .
