Problem
A conveyor belt in a factory moves cartons of goods along a horizontal path at a steady speed of 0.80ms−1 by exerting a constant horizontal force of 150N on each carton.
(i) Starting from the definition of power, derive an expression for the power delivered to a body that moves with uniform velocity under a constant force acting along the direction of motion.
(ii) Using your result of part (i), calculate the power needed to move one carton at the stated speed.
(iii) If a carton remains on the belt for 12s, determine the work done on that carton during this time.
