A particle with m = 3.3E27 kg is moving with a velocity of 6.0E7m/s. It then collides with a stationary particle of mass 2m, the lighter particle then moves at a right angle to the original direction with a velocity of 2.0E7m/s. What is the veloctiy of the heavier particle with (mass 2m).

The heaviercomponent has the original momentum of the moving partical in the horizontal directoni, and the heavier particlehas the opposite momentum vertically to the original particle going up.

Goodness. That is why I gave you instructions to use conservation of Momentum only.
