Physics Lab prediction?

Question

Two gliders have different masses. Glider 2 weighs 3 times as much as glider 1. Assuming glider 2 to be initially at rest as before, describe the final momentum in terms of the initial momentum, both in magnitude and direction for all vector quantities. Approximate the magnitudes of momentum.

m_2=3m_1

u_2=0

Answer 1

v1=3v2
