Suppose that the shuffleboard puck from the "Work" worksheet has a mass of 0.85 kg, starts from rest, and gets released with a speed of 0.60 m/s. Find the change in internal energy of the puck/table/air during the player's push
here,
the mass of puck , m = 0.85 kg
initial speed , u = 0.6 m/s
the kinetic energy gained , KE = 0.5 * m * u^2
KE = 0.5 * 0.85 * 0.6 J
KE = 0.26 J
the change in internal energy of puck is ZERO

(20 pts) On a frictionless, horizontal air table, puck A (with mass 0.15 kg) is moving toward puck B (with mass 0.3 kg), which is initially at rest. After the collision, puck A has a velocity of 0.11 m/s to the left, and puck B has a velocity of 0.65 m/s to the right. (a) What was the speed of puck A before the collision? (b) Calculate the change in the total kinetic energy of the system (A and B)...
