A conveyor belt is used to move sand from one place to another in a factory. The conveyor is tilted at an angle of 14.0° above the horizontal and the sand is moved without slipping at the rate of 7.00 m/s. The sand is collected in a big drum 3.00 m below the end of the conveyor belt. Determine the horizontal distance between the end of the conveyor belt and the middle of the collecting drum.
