In this problem, we're told that the drag force is proportional to v^{2}.

Consider a proportionality constant, k for the drag force.

A baseball is thrown straight up. The drag force is proportional to v^{2}.

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 up? Express your solution with three significant digits, and +y direction is upwards. Omit the unit (m/s^{2}).

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 solution with three significant digits, and +y direction is upwards. Omit the unit (m/s^{2}).
