1.A two story school has interior columns that are spaced 15 ft apartin two perpendicular directions. If the loading on the flat roof isestimated to be 20 lb/ft^2 determine the reduced live loadsupported by a typical interior column at (a) the ground floorlevel, and (b) the second floor level.

2.Ball A is thrown vertically upward from the top of a30-m-high-building with initial velocity of 5m/s. At the sameinstant another ball B is thrown upward from the ground with aninitial velocity of 20m/s. Determine the height from the ground andthe time at which they pass.
