A ball was dropped from rest from level “A” (12 m above the liquid surface, level “B”). Through the liquid,
the ball was applied by deceleration of 120t4 m/s?,
where t is the time in seconds, the ball stopped at level
"C". Calculate:
a) The velocity of the ball at "B"
b) The time taken by the ball from "B" to "C"
C) The distance between "B" and "C"​

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
