1. The problem statement, all variables and given/known data An object is launched and it's velocity upon landing is 12 m/s [13 degrees below the horizontal]. If I assume down is positive and up is negative, what would my given for vf look like? 2. Relevant equations in the x direction: vfcostheta in the y direction: vfsintheta 3. The attempt at a solution vf=-12m/s cos -13 Is it negative 13 b/c it's below the horizontal?
