Acar starts from rest and travels 5.0 s with a uniform acceleration of 1.5 m/s2. the driver then applies the brakes, causing the car to slow down at a rate of 2.0 m/s2. if the brakes are applied for 3.0 seconds, how fast is the car going at the end of the braking period and how far has it gone from the start?

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.
