A14-kg object moving with a constant velocity
of 5.0 m/s overtakes and bumps an 8.0-kg object
moving in the same direction with a constant
velocity of 3.0 m/s. if after impact the 8.0 kg
object has a velocity of 9.0 m/s, calculate the
velocity of the other object.

The image below shows numerous volcanic mountains in the pacific northwest. what is the most likely cause of the volcanic and earthquake activity in this region?

An engine undergoes a cycle as shown in the diagram. during a complete cycle the work done by the gas is 28.5×103 j and the energy transferred thermally out is 99.4×103 j. there are 1.5×1024 gas molecules and they have three active degrees of freedom. 6. (6 pts) during which process(es) is energy transferred thermally into the gas? a. 1→2 b. 2→3 c. 4→1 d. 1→2 and 4→1 e. none of the above
