Activity: A 4M mass that is initially at rest on a frictionless surface explodes into three pieces. If half of the original
mass moves down with a speed of 2v and a quarter of the original mass moves to the left with a speed of v, what is the
velocity of the final quarter of the original mass? Leave the velocity in component form.
Keep in variable form.
