A 0.5 kg block slides from the point A (see fig.) on a
horizontal track with an initial speed of 3 m/s towards
a weightless horizontal spring of length 1 m and force
constant 2 Newton/m. The part AB of the track is
frictionless and the part BC has the coefficients of
static and kinetic friction as 0.22 and 0.2 respectively.
If the distances AB and BD are 2m and 2.14 m
respectively, find the total distance through which the
block moves before it comes to rest completely.
(Take g = 10 m/s2)

Force constant=spring constant?

@*softwared* ...ya it is spring constant..:D

I solved the problem just now..I used the energy principle..:D..If you have any other methods, I am glad to learn:D
