There was a guy in the group that I hit it off with pretty well. I started to like him, and it seemed like he liked me back. Then a group of us went to a cabin together for a weekend where I met a girl in the group that I had not met yet. Apparently the group was trying to set them up because she liked him a lot. A month later they started dating. I backed off, and forgot about my feelings towards the guy. Me and the girl he was dating came to be pretty close friends. Then out of the blue, he broke up with her. She was devastated because she felt completly In Love with him. There were times that she would confide in only me about her feelings because we became very close friends. The problem was that my feelings for him never changed. We hang out often since they broke up, and I can tell that he likes me. I can't help but like him back. I feel like he only started dating her because they had some history before I joined the group and every one wanted them to date. I do feel that he had some feelings for her, so that's why he started dating her. But when he broke up with her, I know that he realized he did not really like her and that it was over for good. My problem is that she is heart broken over this guy, and I really like him. I know he likes me too, but now we have the problem with me being her friend and her trusting me. I don't know what to do because I have liked him since before I even met her, but I really love her. She is my good friend and means a lot to me, And I don't want to hurt her. Is it ok to begin a relationship with my good friends ex? What do I do?</div>Wed, 07 Oct 2015 03:42:38 -05002015-10-07T03:42:38-05:00389526https://www.wyzant.com/resources/answers/150551/sam_is_playing_with_his_slingshot_and_launches_a_rock_straight_up_in_the_air_with_an_initial_upward_velocity_of_120_ft_secCeeCee from Carson City, NVhttps://www.wyzant.com/resources/answers/users/view/86027451Math Word ProblemSam is playing with his slingshot and launches a rock straight up in the air with an initial upward velocity of 120 ft/sec. <div>Gravity slows the rock’s upward velocity and it eventually changes directions and falls back down to the ground.
