# Rotation and Elongation of a spring 1

**Classical Mechanics**Level 5

At the instant \(t=0\) when the spring is in its natural length of \(R\), the mass is given velocity \(V\) in a direction perpendicular to the length of the tube.

If the maximum elongation produced in the spring is \(X\) then find the value of \( (100X^2 + 99)(X+2) \).

In this case, \(m = 2 \text{ kg}, V = 1 \text{ m/s}, k = 200 \text{ N/m}, R = 1 \text{ m} \).
