a mass 2.9kg object moving at a speed of 5.9m\s sticks a mass 0.88kg object initially at rest. immeditaly after the collision the 2.9kg object has a velocity of 0.99m/s directed 27 degree from its initial line of motion. that is the speed of the 0.88kg mass immeditaly after collision?

To work this, consider the conservation of motion in two perpendicular directions. You will find the solution there.
