You and some fellow physics students decide to investigate the concept of moment of inertia foryourselves. You set up an experiment in which you race a number of similarly sized objects down africtionless ramp. The angle of the ramp is  = 20 and the distance the objects slide or roll down theramp is s = 1 m. All the objects are made out of the same type of steel and so are of uniform density.The objects you have are: 1) a solid cube measuring 5 cm on a side and having a mass of 0.98 kg; 2) asolid sphere of 2.5 cm radius and having a mass of 0.52 kg; 3) a hollow sphere with an outer radius of2.5 cm, an inner radius of 1.25 cm, and a mass of 0.45 kg; 4) a spherical shell of 2.5 cm radius and 0.06kg mass; 5) a solid cylinder having a radius of 2.5 cm, a length of 5 cm, and a mass of 0.77 kg; 6) ahollow cylinder of 2.5 cm outer radius, 1.25 cm inner radius, 5 cm length, and 0.58 kg mass; and 7) andtube (cylindrical shell or ring) having a radius of 2.5 cm, a length of 5 cm, and a mass of…

Hi there, I really need some help! I cannot figure out what I am doing wrong. A toy top with a spool of diameter 4.9 cm has a moment of inertia of 3.4×10−5 kg⋅m2 about its rotation axis. To get the top spinning, its string is pulled with a tension of 0.35 N. How long does it take for the top to complete the first five revolutions? The string is long enough that it is wrapped around the top more than five turns. Thank you!
