For a mass oscillating on a spring at what positions are (a) velocity and (b) acceleration of the mass have maximum valeus?

a) At the mean position

b) At the extremes positions

Explanation:

Given that mass is having oscillation motion.

We know that

1. At the mean position - The velocity of the mass is maximum and the acceleration of the mass is minimum. The net force on the mass will be zero.

2. At the extreme position-The velocity of the mass is minimum and the acceleration of the mass is maximum. The net force on the mass will not be zero.

Therefore

a) At the mean position

b) At the extremes positions
