A book is slid across a slick floor starting at velocity tex2html_wrap_inline75 . t seconds later, its velocity is tex2html_wrap_inline77 .

a.
In terms of tex2html_wrap_inline79 , t, and g, find the average acceleration a, the coefficient of friction between the book and the floor tex2html_wrap_inline81 , and how far the book travels during this interval t.
b.
Find a, tex2html_wrap_inline83 and d given tex2html_wrap_inline75 =5.0 meters per second, tex2html_wrap_inline77 =1.0 meters per second, t=4.0 seconds.
