14.A body is moving down a long inclined plane of angle of inclination
?
. The coefficient of friction between the
body and plane varies as
x,
0.5
=
µ
where
x
is the distance moved down the plane. The body will have the
maximum velocity when it has travelled a distance
x
given by :

krishna.gopal

At maxinum velocity dv/dx = 0
as acceleration is v*dv/dx S0 acc = 0
Or mg-(mu)*mg=0
This will happen when mu=1
Or at x=2 meter
