Select the correct expression that gives the block's acceleration at a displacement xxx from the equilibrium position. Note that xxx can be either positive or negative; that is, the block can be either to the right or left of its equilibrium position.a=−kxa=kxa=(k/m)xa=(−k/m)xa=(−k/m)x

Respuesta :

a=(−k/m)x is the correct expression that gives the block's acceleration at a displacement xxx from the equilibrium position.

What is the acceleration at the equilibrium position?

The acceleration of an object is equal to its mass divided by the net force exerted on it, or a = F m, in accordance with Newton's second law of motion. When an object's mass and the net force acting on it are known, its acceleration can be calculated using this equation for acceleration.

There is no restoring force when the mass reaches the equilibrium position. Since there is no acceleration, the mass is traveling at its fastest possible rate. Amplitude is the term used to describe the particle's largest departure from its mean position.
