John is standing at point O at ground level facing east. He throws a ball at an angle of 60° (-radians at an initial velocity of 20 m/s. 1. Decompose the initial velocity Vo, in its x- and y-components (in simplest root form). Final answer: Assume point O is the origin. Write down the vertical position function of the ball, YB (t), assuming that the gravitational acceleration is -9.8 m/s2, as well as the horizontal position function of the ball, xg (t), ignoring air/wind resistance (in simplest root form). Remember: s(t)= at? + vot + So, where vo is initial velocity and So is initial position. 2. Final answer: Y(t) = Xg(t) = %3D 3. What is the maximum height of the ball? Final answer: 4. How long will it take for the ball to be back on the ground?
