1)what is the momentum of a 40,000,000kg tanker traveling at 5 m/s? 2) A particle of mass 10 kg has a momentum of 50 kg m/s .what is the velocity of the particle ?

Help:(

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?
