To strech a spring 6.00cm from its unstreched length, 16.0J of work must be done.
Part A - What is the force constant of this spring?
Part B - What magnitude force is needed to strech the spring 6.00cm from its unstreched length?
Part C - How much work must be done to compress this spring 4.00cm from its unstreched length?
Part D - What force is needed to strech it this distance?
