A package rest on a conveyor belt which is initially at rest . The belt is started and moves to the right for 1.3 s with a constant acceleration of 2 m//s^(2) . The belt then moves with a constant deceleration a_(2) and comes to a stop after a total displacement of 2.2 m . Knowing that the coefficient of friction between the package and the belt are mu_(s) = 0.35 and mu_(k) = 0.25 , determine (a) the deceleration a_(2) of the belt , (b) the displacement of the package relative to the belt as the belt comes to a stop. (g = 9.8 m//s^(2))
