Chemistry Help please!!! Kinetic energy of a rolling billiard ball...?
The kinetic energy of a rolling billiard ball is given by KE=1/2mv^2. Suppose a 0.17-kg billiard ball is rolling down a pool table with an initial speed of 4.7m/s. As it travels, it loses some amount of energy as heat. The ball slows down to 3.7m/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 3.7m/s. Assume the first billiard ball is the system.
Find for the process:
w= ? J
q= ? J
delta E= ? J
Thanks so much for help!
