Tony (of mass 65 kg) coasts on his bicycle (of mass 10 kg) at a constant speed of 5 m/s, carrying a 9 kg pack. Tony throws his pack forward, in the direction of his motion, at 5 m/s relative to the speed of bicycle just before the throw. What is the initial momentum of the system (Tony, the bicycle, and the pack)? Answer in units of kg · m/s.

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 20c 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
