Un auto va frenando y reduce su velocidad de 54 km/h a 25.2 km/h, al recorrer 90 m. Calcula: (a) ¿Cuál será su aceleración, (b) Qué distancia recorrerá antes de alcanzar el reposo, si la aceleración es constante?

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
