Asystem that has 100,000 molecules at energy level 1; 10,000 molecules at energy level 2, and 1000 molecules at energy level 3. what is the entropy of the system?

What is binding energy and separation energy

Abatter hits the baseball a with an initial velocity of v0 = 110 ft/sec directly toward fielder b at an angle of 23° to the horizontal; the initial position of the ball is 2.2 ft above ground level. fielder b requires 0.44 sec to judge where the ball should be caught and begins moving to that position with constant speed. because of great experience, fielder b chooses his running speed so that he arrives at the “catch position” simultaneously with the baseball. the catch position is the field location at which the ball altitude is 8.4 ft. determine the velocity of the ball relative to the fielder at the instant the catch is made.

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
