Question: A package is at rest on a conveyor belt which is initially at rest. The belt is started and moves to the right for 1.5

A package is at rest on a conveyor belt which is initially at rest. The belt is started and moves to the right for 1.5 s with a constant acceleration of 3.2 m/s2. The belt then moves with a constant deceleration 2 a and comes to a stop after a total displacement of 4.6 m. Knowing that the coefficients of friction between the package and the belt are 0.35 μs = and 0.25, μk = determine

(a) The deceleration 2 a of the belt,

(b) The displacement of the package relative to the belt as the belt comes to a stop.
