Consider a solid sphere and a solid disk with the same radius and the same mass. explain why the solid disk has a greater moment of inertia than the solid sphere, even though it has the same overall mass and radius. 2. calculate the moment of inertia for a solid cylinder with a mass of 100g and a radius of 4.0 cm. 3. in this question you will do some algebra to determine two relations that you will need for part 2 of this lab. write down eq. 11 twice. in the first statement, set the rotational kinetic energy term equal to zero (i. e. 1/2iw = 0) – call this your "no krot model". leave the second as it is written in eq. 11 – call this your "krot model". for both models, solve for v in terms of g, h, and a. in the krot model, you will need to use i = kmr2 (eq. 3) and w = v/r. the solution for the krot model will have a k term as well. once you have solved for v, use the kinematic relation, v = at, and solve for t for both models separately. these two solutions represent the predicted time it will take an object to descend a height, h, down an inclined plane when you assume all kinetic energy in the system is translational (no krot model) and when you assume the kinetic energy is distributed betwee
