ooo T-Mobile LTE 1:17 AM @65%. , Done 1 of 2 Oscillation Name: Name: Name: A spring, with spring constant k is attached to the upper comer o a solid block of mass m, as shown in the figure to the right The unstretched spring length is L, and the block rotates around an axis that is also separated from the wall by length L. We are going to calculate the period of this system for smal oscilations 1) As shown below, the sprng has been stretc ed by AL. What s the torque exerted onthe block by the sprng? You may assume that 1 « r. (Give your answer in terms of k, r, L, 1 andior m)? 2) Denve an expression that relates AL with r and the angle through which the block has rotated. You may assume smal arges(thus sin tan 3)Apply Newton's 2" Law for torques to determine an equation for , the angular acceleration. Give your answer only in terms of r, m, k, and or 1· n your final answer.) (Do NOT useExplanation / Answer

Q6) mass = 1.25 kg A = 0.035 m V = 1.55 m/s =============Provided values
K = mv^2 / A = ( 1.25 KG ) * ( 1.55 ) ^2 / 0.035 ^2
K = 2451.530612 N/m====================ANSWER)
