Answer 2

Answer:

Given:

A block strikes the free end of a spring , with Velocity "v". After compressing the spring by a distance"x", the velocity decreases to v/2.

To find:

Maximum Compressions of the spring

Calculation:

We know that spring force is Conservative force and hence the Kinetic energy of the Block will be stored as Potential Energy.

So the following Equation can be created:

$\frac{1}{2} m {v}^{2} = \frac{1}{2} m { (\frac{v}{2} )}^{2} + \frac{1}{2} k {x}^{2} = \frac{1}{2} k {x"}^{2}$

$= > \frac{m {v}^{2} }{4} + k {x}^{2} = k {x"}^{2}$

$= > x" = \sqrt{ \frac{m {v}^{2} }{4k} + {x}^{2} }$

So the max compression is found .
