A stone with a mass of 0.724 kg is dropped from the edge of a cliff. When the stone strikes the ground, the internal energy of the stone and ground increase by 2,307 J. If the stone is initially at rest when it is dropped, how high above the ground is the cliff? (g = 10 m/s2)

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?
