Answer #1

The work that was done to compress the spring will be stored as potential energy in the spring. Now we know that the potential energy stored is given as , where is the distance by which the spring is compressed. So now work done on the spring ,

.( As here ,K= 24 lbs/ft , 1 J=0.738 ft- lb ) .

Hence the work done = 432 J = 318.627 ft-lb.
