Prob. # 1] The mass m = 20 kg is suspended from an ideal spring of stiffness k = 500 N/m, figure P1 below. If the mass is set into motion at t = 0 with the initial conditions x, = 45.5 mm and vo = - 104 mm/s, calculate a) the amplitude of the motion; and b) the time when the mass stops for the first time. Assume that x is measured from the equilibrium position of the mass. PI k = 500 N/m m = 20 kg

Please answer 3, 4, 5, 6, 8, 9, 10, 12 1 is 0, 2 is 0, 7 is point A, 11 is 2. I included a picture of someone who solved but they were mostly incorrect. Please do not answer if the solution set I provided with the incorrect answers was you. I appreciate the attempt, but the solutions for 3, 4, 5, 6, 8, 9, 10, 12 were marked wrong, so unless you have different answers, please do not submit the same incorrect solution set. The wheel is attached to the spring. The mass of the wheel is m=20 kg. The radius of the wheel is 0.6m. The radius of gyration kG=0.4 m. The spring’s unstretched length is L0=1.0 m. The stiffness coefficient of the spring is k=2.0 N/m. The wheel is released from rest at the state 1 when the angle between the spring and the vertical direction is θ=30°. The wheel rolls without slipping and passes the position at the state 2 when the angle is θ=0°. The spring’s length at the state 2 is L2=4 m.
