Q. A 1500-kg submarine rises straight up towards the surface. Seawater exerts both an upward buoyant force of 16480 N on the sub, as well as a downward resistive force of 1160 N. What is the submarine's acceleration?

Q. The deuterium nucleus starts out with a kinetic energy of 2.07e-13 joules, and the proton starts out with a kinetic energy of 4.14e-13 joules. The radius of a proton is 0.9e-15 m; assume that if the particles touch, the distance between their centers will be twice that. What will be the total kinetic energy of both particles an instant before they touch?
