Suppose you have two locations (stations A and B) that are 150km apart from each other. Station A is reporting a surface air pressure of 1023mb while Station B is reporting a surface air pressure of 1014mb. The pressure gradient between two cities would be:

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
