4) An object with mass 3.2 kg is executing simple harmonic motion, attached to a spring with spring constant k = 260 N/m . When the object is 0.012 m from its equilibrium position, it is moving with a speed of 0.55 m/s . Part A Calculate the amplitude of the motion. Express your answer to two significant figures and include the appropriate units. Part B Calculate the maximum speed attained by the object. Express your answer to two significant figures and include the appropriate units.

The analysis of a simple pendulum assumed that the mass was a particle, with no size. A realistic pendulum is a small, uniform sphere of mass M and radius R at the end of a massless string, with I being the distance from the pivot to the center of the sphere. Part A Find an expression for the period of this pendulum. Express your answer in terms of the variables M, R, L, and free fall acceleration g. T= IVE ΑΣΦ Submit Part B Request Answer Suppose M = 25 g, R = 1.0 cm, and L = 1.0 m, typical values for a real pendulum. What is the ratio Treal/Tsimple, where Treal is your expression from part A and T'simple = 2π₁/₂ Express your answer using six significant figures. Treal/Tsimple= ? IVE ΑΣΦ ?
