An animation shows a rotating square. One corner of the square is labeled A. The x and y components of the position of A are each plotted as a function of time on the graphs.

a) During the interval from t = 0 to t = 1.0 s, is the x-component of the average acceleration positive, negative, or zero?
negative
zero
positive - Correct!


b) During the interval from t = 0 to t = 1.0 s, is the y-component of the average acceleration positive, negative, or zero?
zero
positive
negative - Correct!


c) During the interval from t = 0 to t = 1.0 s, is the magnitude of v_x increasing, decreasing, or constant?
constant
increasing
decreasing - Correct!


d) During the interval from t = 0 to t = 1.0 s, is the magnitude of v_y increasing, decreasing, or constant?
constant
increasing - Correct!
decreasing
