When the ball reaches the ground, it hit the ground with 98 J of energy and was travelling at 5 m/s. How much energy did the ball hold even before it was thrown off the wall? What kind of energy is this (be specific)? Explain your answer.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
