Kasim asks Sarah whether there is an acceleration on the system in the y-direction. Which of Sarah's responses is correct? O "Yes, because there are forces in the y-direction, and IF, ma O "No, because the net force in the y-direction is zero." O"Yes, because there is always an acceleration near Earth." O "No, because there are no forces in the y-direction."
