In the arrangement show in figure, the track is frictionless until the body reaches the higher level. A frictional force stops the body in a distance d from A. The initial speed of the body v_(0) is 6 m/s the height h is 1 m and the coefficient of kinetic friction is 0.2. The speed of body at the higher level A is
