A car enters a curve that has a radiusof 30m. The car has a mass of 1450kg. if the maximum force of friction that can act on the car is 5650N what is the maximum velocity that the car can travel through the curve? A 10.8m/s B 7.70m/s C 117m/s D 59.3m/s

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.
