A package is at 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?. Knowing that the coefficients of Coulomb friction between the package and the belt are 4, = 0.35 and µ = 0.25, determine: (a) whether the package slides during that 1.3s time interval; and (b) the work of the friction force on the package during that 1.3s interval.
