Is a.) correct?
Great help is required in the other two.
a.) Fine salt is deposited from a negligible height at a rate of 12kgs-1 onto a conveyor belt moving at speed 8.0ms-1.Calculate the force required to keep the belt moving at this velocity.
b.) A small aircraft of mass 1200 kg which is flying horizontally at 150 ms-1 is taken into a vertical circular path of radius 500m and it is kept in this path until the aircraft makes a complete loop. If the pilot has a mass of 72kg, calculate the force exerted on him by the seat when the aircraft is top and bottom of the loop.
Clueless, much assistance needed here, please.
c.) A lorry of total mass 12000 kg enters a horizontal circular bend of radius 350 m at a constant speed of 45kmh-1.Calculate the magnitude and the direction of the resultant horizontal force acting on the lorry as it travels around the bend
b. Calculate the angle to which the road must be banked in order to provide the same resultant without the need to rely on friction.
