A baseball is thrown straight up. The drag force is proportional to v2. The positive y direction is upward. Part A In terms of g, what is the y-component of the ball's acceleration when its speed is half its terminal speed value and it is moving up? Express your answer as a multiple of acceleration due to gravity. View Available Hint(s) ay = g Part B In terms of g, what is the y-component of the ball's acceleration when its speed is half its terminal speed and it is moving back down? Express your answer as a multiple of acceleration due to gravity. View Available Hint(s) ay = g
