A particle of mass m, moving in a circular path of radius R with a constant speed v₂ is located at point (2R, 0) at time t = 0 and a man starts moving with a velocity v₁ along the positive y-axis from origin at time t = 0. Calculate the linear momentum of the particle w.r.t. man as a function of time.
