A helicopter is flying horizontally at a speed of 60 m/s and accidentally drops a storage pod from an elevation of 300 m. Neglect air resistance, find how long does it take for the storage pod to hit the ground and calculate the total distance the storage pod covers horizontally just before it hits the ground?
Two water reservoirs are open to the atmosphere. The manometer contains mercury with the density of 13,600kg/m cubed. What is the difference in elevation if the manometer reading is 25cm.
