2) A particle with positive charge q and mass m moves in a uniform constant magnetic eld that points in the z direction, B 2 Bi. The charge is subject to a linear drag force bv. (:1) Find the velocity of the particle, v(t), if its initial velocity is v9; {b} Find the time dependence of the kinetic energy,r of the particle, EU) : m[o(t}]2f2. Partial answer: y[t) = e""'(g}u eos(mt) in sin(mt)), Where 1' = mfb and (a = fom
