). A particle of mass 0.2 kg moving along the x-axis has position r and speed v at time t. At time t = 0 s, v = 0 m s-1 and r = 1 m. The particle moves under the action of a force in the direction of increasing r and of magnitude (1) n. (a) Assuming no other forces act on the particle show that: V = 40 ln(2) са (b) Assuming a constant resistive force of 2 N acts on the particle whenever it is moving show that the maximum speed Vmax the particle can reach is: Umar = 20(2 ln 2 – 2) CU
