Heh, this isn't complex at all. In high school, especially since your physics class just started, you won't have air resistance. You should be able to do this easily if you read the material or listen to the teacher in class. Do you have all of your kinematic equations memorized?
The problem says at a constant speed, therefore a=0. Also, there is no friction slowing you down. F=ma, a=0, so the net force is zero. You need to find the vertical and horizontal components of the applied force. So F(applied)*cos(27)=F(applied,horizontal), and F(applied)*sin(27)=F(applied...
