1. The problem statement, all variables and given/known data A spring of stiffness k is attached to a wall and to the axle of a wheel of mass m, radius R, and moment of inertia I = βmR^2 about its frictionless axle. The spring is stretched a distance A and the wheel is released from rest. Assume the wheel rolls without slipping. At some moment, the horizontal component of the spring force on the wheel is Fx, fid the magnitude and direction of: The friction force The acceleration of the wheel's center of mass The angular acceleration of the wheel about its CM 2. Relevant equations F = -kx τ = Iα E = (1/2)kx^2 3. The attempt at a solution I'm really not even sure how to start this problem and how to set it up. I've always struggled with rotational motion intuitively, so I'm having trouble relating it to SHM.
