When an object oscillating in simple harmonic motion is at its maximum displacement from the equilibrium position, which of the following is true of the values of its speed and the magnitude of the restoring force?

speed maximum

restoring force minimum

Explanation:

When the particle executing SHM is at its mean position or equilibrium position, then its velocity is maximum and the kinetic energy is also maximum. It is because the kinetic energy is proportional to the square of the velocity as velocity maximum then kinetic energy is also maximum.

The acceleration is minimum at the equilibrium position so the restoring force is also minimum t its equilibrium position.

mL

Explanation:

cm is a unit of length

cm³ is a unit of volume, but it is usually used for solids

kg is a unit of mass

mL is a unit used to measure the volume of a liquid

Hope this helps!
