Homework Help: Thermochemistry

Posted by Kyle on Friday, October 30, 2009 at 4:54pm.

Suppose a 0.17-kg billiard ball is rolling down a pool table with an initial speed of 4.5 m/s. As it travels, it loses some of its energy as heat. The ball slows down to 3.5 m/s and then collides straight-on with a second billiard ball of equal mass. The first billiard ball completely stops and the second one rolls away with a velocity of 3.5 m/s. Assume the first billiard ball is the system.

Calculate w for the process.

Calculate q for the process.

Calculate delta E for the process.
