A long spring is hung vertically with a weight attached to the bottom. Once the spring has stopped moving, the weight is pulled down exactly 0.998 meters and released. The time taken for the spring to perform exactly one "bounce" cycle is 8.13 seconds.

What is the displacement from rest position, the velocity and the acceleration of the weight 79.56 seconds after being released?

-You will need to create an appropriate equation.

- Assume that no energy is lost to heat, noise etc and that the motion is simple harmonic. - Make DOWN to be the NEGATIVE direction and UP to be the POSITIVE direction.

eg: The weight is initially displaced -0.998 meters.

Round all values to FOUR decimal places.

Displacement = m

Velocity = ms-1

Acceleration = ms-2

thanks guys :)
