You're a production engineer in a cookie factory, where mounds of dough drop vertically onto a conveyer belt at the rate of one 14 mound every 2 seconds. You're asked to design a mechanism that will keep the conveyor belt moving at a constant 46.
A) What average force must the mechanism exert on the belt? Express your answer using two significant figures.
