Physics Sand On Conveyor Belt Pictures

Kinetic Energy, work and force! Sand conveyor problem ...

Apr 15, 2012· If kinetic energy is the work done in giving an object a certain velocity, can I calculate the work done per second on the sand on the conveyor belt using the KE formula? So. mass* velocity^2/2= 60 kg (mass of sand) * 2 m/s *1/2 = 120 watts

Approaches to Sand on a Conveyor Belt

When the sand falls on the belt in order to accelerate the sand to the same velocity as the belt there must be frictional forces between the sand and the belt. There must also be relative movement between the belt and the sand during this acceleration phase as the sand cannot instantaneously to the velocity of the belt.

Sand from a stationary hopper falls onto a moving conveyor ...

Sand from a stationary hopper falls onto a moving conveyor belt at the rate of 5.00 kg/s as shown in Figure P9.52. The conveyor belt is supported by frictionless rollers and moves at a constant speed of v = 0.750 m/s under the action of a constant horizontal external force F → ext supplied by the motor that drives the belt. Find (a) the sand's rate of change of momentum in the horizontal ...

Physics question on energy. help please? | Yahoo Answers

Oct 11, 2015· A conveyor belt is driven at velocity v by a motor. Sand drops vertically on to the belt at a rate of m kg s–1. What is the additional power needed to keep the conveyor belt moving at a steady speed when the sand starts to fall on it? I get the answer as 0.5mv^2 as the kinetic energy gained by m kg of sand per second is 0.5mv^2 therefore it is equal to the power given but the answer is wrong ...

Solutions

The force allows the sand to be carried at a constant speed, even if the changing mass on top of the conveyor belt is increasing. Because of the conservation of the momentum, the rate of change in the momentum of the conveyor belt induced by the falling sand is also equal to the rate of change of the falling sand.
