Astone is dropped at t = 0. a second stone, with 6 times the mass of the first, is dropped from the same point at t = 190 ms. (a) how far below the release point is the center of mass of the two stones at t = 370 ms? (neither stone has yet reached the ground.) (b) how fast is the center of mass of the two-stone system moving at that time?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
