As a mass on a spring moves farther from the equilibrium position, how do the velocity, acceleration, and force change?

a the velocity decreases, the acceleration decreases, and the net force decreases.
b the velocity increases, the acceleration decreases, and the net force decreases.
c the velocity increases, the acceleration increases, and the net force decreases.
d the velocity decreases, the acceleration increases, and the net force increases.

Answer

d The velocity decreases, the acceleration increases, and the net force increases.

Explanation

When the spring is in equilibrium, the velocity is zero. So, no acceleration hence no force since force is a product of acceleration.

Force = Mass × acceleration

F=ma

For it to move from equilibrium position is require a force. When the force increases the acceleration must be increasing. The velocity will be decreasing since force a spring it requires a large force to produce a change in velocity.
