Chapter 1: Q2-30E (page 1)
A cat walks in a straight line, which we shall call the \(x\)-axis, with the positive direction to the right. As an observant physicist, you make measurements of this cat’s motion and construct a graph of the feline’s velocity as a function of time (Fig. E2.30). (a) Find the cat’s velocity at \(t = 4.0\,s\) and at \(t = 7.0\,s\).
Short Answer
Hence, the required velocities are
\({v_{4\,s}} = 2.68{\rm{ cm/s and }}{v_{7\,s}} = 1.31{\rm{ cm/s}}\).
