When an object moving in simple harmonic motion is at its maximum displacement from equilibrium, which of the following is at a maximum? (a) velocity, (b) acceleration, or (c) kinetic energy

To determine
The quantity which is maximum for an object in simple harmonic motion at its maximum displacement from equilibrium

Explanation

From Hooke’s law,

F=k.x

Here,

F is the force

k is force constant

Conclusion:

Simple harmonic motion follows the Hooke’s law. From the Hook’s law it is clear that the force is maximum when the object is in its maximum position. Since force and acceleration are proportional to each other, acceleration will be maximum for the object in its maximum displacement position
