Jack (mass 55.0 kg) is sliding due east with speed 8.00 m/s on the surface of a frozen pond. He collides with Jill (mass 44.0 kg), who is initially at rest. After the collision, Jack is traveling at 5.00m/s in a direction 34.0∘ north of east. Ignore friction.
a) What is the direction of the Jill's velocity after the collision? Express your answer in degrees.
b)What is the magnitude of the Jill's velocity after the collision? Express your answer with the appropriate units.
This problem is based on momentum conservation principle. By applying momentum conservation we can solve this problem.
a) : The direction of Jill's velocity after the collision is 35.94 degree towards south.
b): The magnitude of Jill's velocity after the collision is 5.95 m/s.
