A 0.110-kg ball (ball x) moving at 1.20 m/s to the right, collides head-on with an identical ball (ball Y) moving to the left at a velocity of 0.600 m/s. Ball Y rebounds and reverses direction at a velocity of 0.800 m/s. What is the velocity of ball X following the collision?
A 0.200 m/s to the left
B. 0.0924 m/s to the right
C. 0.0880 m/s to the right
D. 0.00440 m/s to the left

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
