In outer space a rock with mass 7 kg, and velocity < 4000, -3200, 2600 > m/s, struck a rock with mass 13 kg and velocity < 260, -320, 180 > m/s. After the collision, the 7 kg rock's velocity is < 3500, -2600, 2900 > m/s.
What is the final velocity of the 13 kg rock?
Vf= <?,?,?> m/s
What is the change in the internal energy of the rocks?
deltaEinternal= (Answer in Joules)
Which of the following statements about Q (transfer of energy into the system because of a temperature difference between system and surroundings) are correct? Check all that apply:
Q= deltaK of the rocks
Q= the change in internal energy of the rocks
Q is very close to zero because duration of the collision was very short
Q is very close to zero because there are no significant objects in the surroundings
