Suppose the speed of the car is 11.1 m/s (equivalent to 25mph) and the radius of curvature (r) is 25 m; determine the magnitude of the centripetal acceleration of the car.

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the
