An 85.0 kg man, sitting in a 110 kg canoe, catches a 5.0 kg cooler, tossed at 5.0 m/s by a friend. a. Is the collision elastic or inelastic? Explain.
b. What is the final velocity of the canoe?

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
