Question

2. A conveyor lifts de-icing salt from 3 feet above ground to a height of 17 feet, then drops it, forming a conical pile 14 feet high and 45 feet in diameter. Assume the weight density of the salt is 80 lbs/ft (a) Find the total work done by the conveyor in lifting the salt. (b) Find the total work done by the force of gravity in moving the salt into its conical shape as it drops from the end of the con veyor. (For simplicity, assume the grains of salt do not bounce.)
