Best ResponseYou've already chosen the best response.0the force which the belt must exert on the sugar to accelerate it to the speed of the belt?

Best ResponseYou've already chosen the best response.0ill give you a hint .. the sugar momentum changes when i gets on the belt use F = dp/dt and find out the force that the belt exert's on the sugar

Best ResponseYou've already chosen the best response.0now how do we demonstrate this in the diagram, becoz the weight down the slope should also be considered..

Best ResponseYou've already chosen the best response.0i think we should add the weight (affective part due to the angle) to the dp/dt term

Best ResponseYou've already chosen the best response.0the dp/dt part acts for a short time

Best ResponseYou've already chosen the best response.0so where is force exerted on the sugar by belt?

Best ResponseYou've already chosen the best response.0the dp/dt is just to give it a speed of 3ms and the mgx is always there

Best ResponseYou've already chosen the best response.0You need to consider total momentum before and after an elementary mass dm of sugar joins the conveyor belt.

Best ResponseYou've already chosen the best response.0so you have 18 * 9.8 * sin(20) + 18 * 3 = 114.33

Best ResponseYou've already chosen the best response.0cool sector, i just need a system showing all this forces so tht i can resolve each of them and find force? is i possible?

Coolsector

Best ResponseYou've already chosen the best response.0this is the system that shows the forces on the sugar at the moment it touches the belt!

Best ResponseYou've already chosen the best response.0you can give the dp/dt a different name maybe it will look better for you.. the thing to understand is that at the moment of touch the belt exerts dp/dt + mgx on the sugar
