Q. A mercury barometer reads 743 mm on the roof of a building and 766 mm on the ground. Assuming a constant value of 1.29 kg/m3 for the density of air, determine the height of the building.
Q. A 0.015-kg bullet traveling horizontally at 400.2 m/s strikes a 4.1-kg block of wood sitting at the edge of a table. The bullet is lodged into the wood. If the table height is 1.2 m, how far from the table does the block hit the floor?
