He calculation of kinetic energy uses the formula, ke = 1 2 mv2. identify the unit that is required for mass and velocity, respectively, to determine the kinetic energy in joules.

Aparticle with mass 1.81×10−3 kg and a charge of 1.22×10−8 c has, at a given instant, a velocity v⃗ =(3.00×104m/s)j^. what are the magnitude and direction of the particle’s acceleration produced by a uniform magnetic field b⃗ =(1.63t)i^+(0.980t)j^?
