### Sand drops on conveyor belt | Physics Forums

"Sand from a stationary hopper falls on a moving conveyor belt at a rate of 5.81 kg/s. The belt is supported by frictionless rollers and moves at .645 m/s under the action of a horizontal external force supplied by the motor that drives the belt." 1. Find the sand's rate of change of momentum in the horizontal direction (answer in units of N) 2.

5. Sand is dumped off a conveyor belt into a pile at the rate of 2 cubic feet per minute. The sand pile is shaped like a cone whose height and base diameter are always equal. At what rate is the height of the pile growing when the pile is 5 feet high? (The volume of a cone is år2h where r is the radius of the base and h is the height.)

### Sand drops fall vertically at the rate of 2kg/sec on to a ...

recategorized Mar 7 2020 by subrita. Sand drops fall vertically at the rate of 2kg/sec on to a conveyor belt moving horizontally with the velocity of 0.2 m/sec. Then the extra force needed to keep the belt moving is. (A) 0.4 Newton. (B) 0.08 Newton.

### Sand drops fall vertically at the rate of 3 kg/s on the ...

Explanation: Force generated due to falling of sand on the conveyor belt is. V dm dt. I.e (0.25 ⋅ 3) N or 0.75 N. Sothis amount of force will be required per second to help per meter movement of the belthence extra power that would be required is P = F ⋅ v = (0.75 ⋅ 0.25) or 0.18 watt. Answer link.
