Object 1 has a mass m1 and a velocity vector v 1 = (2.87 m/s)xhat. Object 2 has a mass m2 and a velocity vector v 2 = (3.06 m/s)yhat. The total momentum of these two objects has a magnitude of 18.6 kg · m/s and points in a direction 66.5° above the positive x-axis. Find m1 and m2.

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
