Determine the frictional force-includingsign

Reference no: EM13564121

Luggage is transported from one location to another in an airport by a conveyor belt. At a certain location, the belt movesdown an incline that makes an angle of 1.7° with the horizontal. Assume that with such a slight angle there is noslipping of the luggage. Determine the frictional force, includingsign, by the belt on a box weighing 60 N when the box is on the inclined portion of the belt and the belt speed is(a) 0 and constant, (b) 0.65 m/sand constant, (c) 0.65 m/s and increasing at arate of 0.16 m/s², (d) 0.65 m/s anddecreasing at a rate of 0.16 m/s², and(e) 0.65 m/s and increasing at a rate of 0.53m/s². Take the positive direction to be up the incline.
