A solid sphere of mass m1=1.0 kg and a hoop of mass m2=2.0 kg, and the same radius r = 0.3 m are released simultaneously from heights h, and h2, respectively, and roll without friction on a cylindrically-shaped surface, as shown in the figure. If the ratio of h1/h2=7/10 then the two objects collide: m2 mi R h2 = R V.. Select one: O a. closer to the release point of m, O b. closer to the release point of m2 O c. in the middle O d. cannot determine (surface radius R is needed)
