At time t = 0, a projectile is launched from ground level. at t = 2.00 s, it is displaced d = 52 m horizontally and h = 55 m vertically above the launch point. what are the (a) horizontal and (b)
vertical components of the initial velocity of the projectile? (c) at the instant it reaches its maximum height above ground level, what is its horizontal displacement d from the launch point?

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
