Two hockey pucks are initially at rest on a horizontal plane of frictionless ice. Puck A has twice the mass of puck B. Suppose we apply the same constant force on each puck until each puck has crossed a finish line 1 m away from its starting point. How do the puck’s kinetic energies compare when each crosses the finish line?
A. KA = 4KB
B. KA = 2KB
C. KA = KB
D. KB = 2KA
E. KB = 4KA
F. Some other relationship (specify)
C. KA = KB

Which statement below regarding the First Law of Thermodynamics is most correct?
a. A system can do work externally only if its internal energy decreases. b. The internal energy of a system that interacts with its environment must change. c. No matter what other interactions take place, the internal energy must change if a system undergoes a heat transfer. d. The only changes that can occur in the internal energy of a system are those produced by non-mechanical forces. e. The internal energy of a system cannot change if the heat transferred to the system is equal to the work done by the system.
