Consider two pool balls sliding frictionlessly across a pool table. Before the collision, ball 1 slides leftward at 2.0 m/s, and ball 2 is motionless. After the ”head-on” collision,ball 1 slides leftward at 0.50 m/s. Both balls have mass m = 0.10 kg. (a) What is thevelocity (speed and direction) of ball 2 after the collision? (b) During the collision, theballs heat up slightly. How many joules of ”dissipated” energy (e.g. heat
