An unhappy rodent of mass 0.289kg , moving on the end of a spring with force constant 2.52N/m , is acted on by a damping force Fx=?b?vx.
a. If the constant b has the value 0.894kg/s , what is the frequency of oscillation of the mouse?
b. For what value of the constant b will the motion be critically damped?
