Q$3(14-22$ in text$)$

The $25$ lb block has an initial speed of $10f\frac{t}{s}$ when it is midway between springs A and $B.$ After striking spring $B,$ it rebounds and slides across the horizontal plane toward spring $A,$ etc. If the coefficient of kinetic friction between the plane and the block is $0\mathrm{.}4,$ determine the total distance traveled by the block before it comes to rest.

Ans: $4\mathrm{.}73$ ft
