A little cat, Bella, walks along a straight line, which we shall call the axis, with the positive direction to the right. As an observant scientist, you make measurements of her motion and construct a graph of the little feline's velocity as a function of time. (See the figure (Figure 1).) Figure Ux (cm/s) 6 4 2 1 2 3 4 5 6 t (s) 1 of 1 Part A Find Bella's velocity at t = 3.0 s. Express your answer in centimeters per second to two significant figures.
