An ice hockey puck of mass 170 g enters the goal with a momentum of < 0,0, -6.6 > kg·m/s, crossing the goal line at location < 0,0, -29 > m relative to an origin in the center of the rink. the puck had been hit by a player 0.4 s before reaching the goal. what was the location of the puck when it was hit by the player, assuming negligible friction between the puck and the ice? (note that the ice surface lies in the x⁢z plane. express your answer in vector form.)

Water at room temperature of 20.0°c is poured into an aluminum cylinder which has graduation markings etched on the inside. the reading in the graduations is 300.0 cc. the cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100°c. what is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? the volume coefficient of expansion of water is 2.07 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc
