Question

A block is attached to an ideal spring. The spring is horizontal, and the block is on a frictionless surface. The block is released from rest when the spring is stretched by a distance of A from its natural length, and the block then oscillates in one dimension with an angular frequency w1. An identical block is then attached to an identical horizontal spring, with this block supported by the same frictionless surface. This second block is released from rest when the spring is stretched by a distance of 2A from its natural length, and this block then oscillates in one dimension with an angular frequency w2.

How do the two angular frequencies compare?

Explanation / Answer

frequency depends upon mass and k

and doesnot depend on gravity

so w1 = w2
