Re: HRW CH 10. Problem 57

["D.V.N.Sarma" <hyd1_narayana@SANCHARNET.IN>]

Answers to (b) and (c) follow if we take normal reaction of ground to
be 6 times the weight. Compression of 0.3 m includes not only the
one due to the down ward motion of the body but also due to the
weight of the body. For (a) is the answer 5 times the weight of the
body justified?

Sarma.
