5) Starting from rest, a penny (mass mp and radius rp), a nickel (mass mn and radius rn), and a marble (mass mm and radius I'm) each roll without slipping down a ramp of height 40 cm. a. At the bottom of the ramp, how will their final speeds compare? Make a conceptual argument; no equations are necessary for this part. b. Now, solve for the final speed of each object. (You will get a numerical value.) c. Was your answer to part a correct? If not, explain. 5) Starting from rest, a penny (mass mp and radius rp), a nickel (mass mn and radius rn), and a marble (mass mm and radius I'm) each roll without slipping down a ramp of height 40 cm. a.
