A baseball is thrown at an angle of 30 degrees relative to the ground at a speed of 27m/s. If the ball was caught 43.0 m from the thrower, how long was it in the air? How high above the thrower did the ball travel

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.
