Moves with simple harmonic motion over a horizontal frictionless surface. At the instant that it is displaced from equilibrium by -0.050m, what is its acceleration?
A wheel free to rotate about its axis that is not frictionless is initially at rest. A constant external torque of +60 N·m is applied to the wheel for 23 s, giving the wheel an angular velocity of +520 rev/min. The external torque is then r
