Fred the otter climbed to the top of an inclined plane. His friend, Giselle the giraffe, suggested that he was so small that gravity would ignore him and he would be unable to slide down. "On the contrary", said Fred, "Since this slope makes an angle of 48.4 degrees with the horizontal and I have a mass of 3.8 kilograms, the magnitude of the component of my weight that acts parallel to the slope is equal to..." Fred knew how to calculate this, can you? Please enter the magnitude of the component of Fred's weight that is parallel to the incline in Newtons. DO NOT ROUND
