Two cars collide at an intersection. Car A, with a mass of 2000 kg , is going from west to east, while car B, of mass 1400 kg , is going from north to south at 13.0 m}/ s . As a result of this collision, the two cars become enmeshed and move as one afterwards. In your role as an expert witness, you inspect the scene and determine that, after the collision, the enmeshed cars moved at an angle of 65.0degrees south of east from the point of impact.
A. How fast were the enmeshed cars moving just after the collision?
B. How fast was car A going just before the collision?
Consider two systems, each containing an ideal gas with N particles kept at the same temperature, but different pressures P1 and P2. After reservoirs are combined together what is the change of the entropy? Try to solve this problems in few steps:..
