[+x 35 +y] is basically the same as [East 35 North] and [-y 60 +x] is [South 60 East].
I found the velocity of the first mass using this equation,
V1f = (m1-m3/m1+m3)v1i + (2*m3/m1+m3)v2i
The answer came up to be 9 m/s [East 80 North]
What next?
Homework Statement
Two masses, m1 = 4 kg and m2 = 12 kg, have initial velocities of v1i = 28 m/s [+x 35 +y] and v2i = [-y 60 +x]. If the first mass has a final velocity of v1f = 18 m/s [-y 40 +x], find:
a). The final velocity of m2.
b). Whether or not the collision can be said to be...
