A ball is thrown straight down with an initial speed of 2.0 m/s from a height of 15 m. Which of the following is the correct relationship in determining the position of the ball after 3.0 s? Use g = 9.8 m/s². Ⓒyf= (15 m) + (-2.0 m/s) (3.0 s) + 0.5*(-9.8 m/s²)(3.0 s)² O yf=(-15 m) + (-2.0 m/s) (3.0 s) + 0.5*(-9.8 m/s²)(3.0 s)² Ⓒyf= (15 m) + (2.0 m/s) (3.0 s) + 0.5*(9.8 m/s²)(3.0 s)² O yf= (-15 m) + (2.0 m/s) (3.0 s) + 0.5*(-9.8 m/s²)(3.0 s)² Oyf (15 m) + (-2.0 m/s) (3.0 s) + 0.5*(9.8 m/s²)(3.0 s)² Ⓒyf= (15 m) + (2.0 m/s) (3.0 s) + 0.5*(-9.8 m/s²)(3.0 s)²
