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

Sand drops fall vertically at the rate of 2 kg/sec on to a conveyor belt moving horizontal with a velocity 0.2 m/s. Then the extra force required to keep the belt moving 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 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 rate which work is done by friction force on sand is
