Question 19 (4 points) A 2-kg ball traveling in the y-direction (North) collides with a 6-kg ball, initially at rest. After the collision, the 6-kg ball is moving at 5 m/s, 53° West of North. The 2-kg ball is moving 37° East of North. 6 kg 530 5 m/s 379 VE 2 kg before 6 kg after 2 kg What was the initial speed of the small ball (before the collision)? 20 m/s 35 m/s 30 m/s 15 m/s 40 m/s 10 m/s 25 m/s
