Abody a of mass 1.5kg, travelling along the positive x-axis with speed 4.5m/s, collides with another body b of mass 3.2kg which, initially, is at rest. as a result of the collision, a is deflected and moves with a speed 2.1m/s in a direction which is at angle 30° below the x-axis. b is set in motion at an angle θ above the x-axis. calculate the velocity of b after the collision

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.
