Answer:
The 43kg student will be sliding at 1.79m/s opposite the direction the 34kg student is going.
Explanation:
Conservation of linear momentum!
The law of conservation of momentum says that in an isolated system, the momentum before must equal the momentum after:
.
For our two students
(notice the - sign in -2.4m/s, this means going to the left)
since the students were not moving at first, , therefore we have
solving for gives
Hence the 43kg student will be sliding at 1.79m/s to the right.
