2. If we place another identical ball onto the table, the situation changes. Now there is one ball with energy, and one that is not moving (its speed is
0 m/s). Calculate the total thermal energy of the system by adding the
energy of each ball.

An astronaut on the moon throws a baseball upward. the astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 3030 ft per sec. the height s of the ball in feet is given by the equation s equals negative 2.7 t squared plus 30 t plus 6.5s=−2.7t2+30t+6.5, where t is the number of seconds after the ball was thrown. complete parts a and b.
