A long jumper leaves the ground with an initial velocity of 12 m/s at an angle of 28-degrees above the horizontal. Determine the time of flight, the horizontal distance, and the peak height of the long-jumper. Don’t answer the question I just want to know if the VYF AND VYI are gonna be negative or positive. I know they’re the same number as the initials ones but I don’t know if it’s negative
