Question 2 Radius R Hoop Cylinder Sphere All mass M h The figure above shows a solid sphere, cylinder, and hoop, all of the same mass and radius. If they are released from the top of the incline from rest, which object will reach the bottom first? O The sphere. O All three objects will reach the bottom at the same time. O The cylinder. O The hoop.Question 3 y A B 10 cm 10 cm C X The three objects shown in the figure above have masses given by . A: 240. g . B: 270. g C: 70.0 g. They are connected by massless, rigid rods. What are the coordinates of the centre of mass? O (0 cm, 0 cm) O (3.40 cm, 5.10 cm) O (6.67 cm, 6.67 cm) O (5.86 cm, 8.79 cm)Question 4 A 10 cm 10 cm B C X 12 cm The three objects shown in the figure above have masses given by . A: 240. g . B: 50.0 g . C: 350. g. They are connected by massless, rigid rods. Find the moment of inertia about an axis that passes through mass A and is perpendicular to the page.
