1) Draw a diagram
2) Label the angle phi
What conservation principle can you use to solve this problem?

anonymous · Answer

i dont know we havent really even studied this. he just told us to figure out how to do it in our book and i dont understand

surry99 · Answer

ok you need to look up conservation of linear momentum.
