Projectile Motion With Unequal Launch And Landing Height

[QUOTE="2slowtogofast, post: 5003463, member: 74152"] The initial velocity makes an angle of 60 degrees with the x axis. That is clear from the diagram from the book. In my attempt at the solution I drew the x',y' coordinate system rotated 20 degrees CCW from x,y. I did this so the launch height and the landing height would be the same. The 70 degrees comes from the component of acceleration from gravity that acts in the x' direction. If it was just x,y obviously gravity would be only in the -y direction but since I aligned my co-ordinate system with the 20 degree inclined plane shown in the problem I had to compensate for that. This could be where I went wrong and that is why I am asking. [/QUOTE]
