1.A submerged stratum of clay has a thickness of 15m. The average water content of samples taken from the stratum is 54%, and the specific gravity of the solid constituents is 2.78. What is the effective vertical pressure, due to the weight of the clay, at the base of the stratum.

2.The initial velocity of a 15-lb block is given as mv1=15i+15j (ft/s). A force defined by F=250i-250tj (lb) acts on the particle from time t=0 to time t=0.3 s for a total duration of 0.3 s. Determine the particle’s velocity at t=1 s. Neglect friction.
