Problem 2.3

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 cats motion and construct a graph of the felines velocity as a function of time (Fig. E2.30). (a) Find the cats velocity at t = 4.0 s and at t = 7.0 s. (b) What is the cats acceleration at t = 3.0 s? At t = 6.0 s? At t = 7.0 s? (c) What distance does the cat move during the first 4.5 s? From t = 0 to t = 7.5 s? (d) Assuming that the cat started at the origin, sketch clear graphs of the cats acceleration and position as functions of time.

Chapter 2 Notes When mass is at an equilibrium and the spring is stretched in equilibrium the force of gravity balances the elastic force from a spring. The elastic force depends on the elongation of our string F= -kx Where x is elongation and k is the stiffness or spring constant. K depends on thickness of the wire as well as on the material our spring is made of. Please note the...
