I believe I have the problem figured out, thank you for the help all those who posted. Btw, vi is a initial velocity, not a force. This wans a typo, sorry. My conclusion is that the object does indeed take longer to fall. The times cannot be equal because that is not an answer choice...

I apologize if I seem incompetent, but I don't entirely follow. I understand that the drag force will cause the magnitude of the acceleration to decrease throughout the motion. The initial acceleration will have a magnitude of g+kvi/m. As velocity diminishes, this value will reach g when v=0...

the equation arctan(y/x) will give you the measure of the angle off the x-axis in the counter clockwise direction.

Homework Statement A ball of mass "m" is thrown vertically upward with a velocity of "vi." It experiences a force of air resistance given by F=-kv, where "k" is a positive constant. The positive direction for all vector quantities is upward. Does it take longer for the ball to rise to its...
