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).) What is her acceleration at t= 4.0 s? Express your answer in centimeters per second squared to two significant figures. 15. ΑΣΦ ax=0.68 ? cm/s²
