A 45,000 kg freighter has a momentum of 150,000 kg∙m/s towards the north. What is the magnitude and direction of its velocity? HELP I NEED THIS ASAP.

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
