A hopper drops gravel at a rate of 75 kg/sec onto a conveyor belt moving at a constant speed v = 2.2 m/sec. Find power output must the motor have that drives the conveyor belt ?

Sand drops from a stationary hopper at the rate of 5kg//s on to a conveyor belt moving with a constant speed of 2m//s . What is the force required to keep the belt moving and what is the power delivered by the motor, moving the belt?

A car of mass m 1600 kg, while moving on any road, experience resistance to its motion given by (m+nV^(2)) newton, where m and n are positive constants. On a horizontal road the car moved at a constant speed of 40 m/s when the engine developed a power of 53 KW. When the engine developed an output of 2 KW the car was able to travel on a horizontal road at a constant speed of 10 m/s. (a) Find the power that the engine must deliver for the car to travel at a constant speed of 40 m/s on a horizontal road. (b) The car is able to climb a hill at a constant speed of 40 m/s with its engine working at a constant rate of 69 KW. Calculate the inclination of the hill (in degree)

Sand particles drop vertically at the rate of 2kgs^-1 on a conveyor belt moving horizontally with a velocity of 0.2ms^-1 . The extra force required to keep the belt moving is

Sand particles drop vertically at the rate of 2kgs^-1 on a conveyor belt moving horizontally with a velocity of 0.2ms^-1 . The extra force required is

A block is gently placed on a conveyor belt moving horizontal with constant speed After t = 4s the velocity of the block becomes equal to velocity of the belt If the coefficient of friction between the block and the belt is mu = 0.2 , then the velocity of the conveyor belt is .

Sand is droped vetically downward at the constant rate mu kg//s on a conveyor belt which is moving horizontally with velocity 'v' . Assume that sant particles comes to rest with respect to belt immediately after landing. The magnitude of force must be applies on the belt moves with same constant velocity v .

Sand particles drop vertically at the rate of 2kgs^-1 on a conveyor belt moving horizontally with a velocity of 0.2ms^-1 . The time rate of change of kinetic energy of sand particles is

Sand is droped vetically downward at the constant rate mu kg//s on a conveyor belt which is moving horizontally with velocity 'v' . Assume that sant particles comes to rest with respect to belt immediately after landing. The rae at which work is done by the external force applied on the belt.
