This is velocity, that is my velocity right over there and I'm starting off at 5 m/s this is 5 m/s right over here so V_i is equal to 5 m/s and then every second that goes by, I'm going 2 m/s faster because it's 2 meters per second per second! so every second that goes by so after 1 second...I'm going to go 2 m/s faster...so I'll be at 7
