EXE.1A.HL.TZ0.1
Two bodies collide on a horizontal frictionless surface. Body X, of mass 2.0 kg, moves with an initial speed of 0.80 m s−1 and body Y is initially stationary. After the collision, body X moves at an angle of 90° to the initial direction of motion with a speed of 0.60 m s−1.
What is the magnitude of the momentum of body Y after the collision?
A. 0.40 kg m s−1
B. 1.0 kg m s−1
C. 2.0 kg m s−1
D. 2.8 kg m s−1
