35. In Chapter 1 acceleration is defined as a = ∆v. Show ∆t that on an inclined plane, the acceleration of a cart that gains 6.0 m/s each 1.2 s is 5.0 m/s2.
36. In this chapter we learn that the cause of acceleration is given by Newton’s second law: a = Fnet/m . Show that the acceleration in Problem 35 results from a net force of 15 N exerted on a 3.0-kg cart. (Note: The unit N/kg is equivalent to m/s2.)
