A body of mass m is launched up on a rough inclined plane making an angle 45^(@) with horizontal If the time of ascent is half of the time of descent, the frictional coefficient between plane and body is

A body of mass ‘m’ is launched up on a rough inclined plane making an angle of 30^(@) with the horizontal. The coefficient of friction between the body and plane is (sqrt(x))/(5) if the time of ascent is half of the time of descent. The value of x is ___________.

A body is pushed up on a rough inclined plane making an angle 30^(@) to the horizontal. If its time of ascent on the plane is half the time of its descent. Find coefficient of friction between the body and the inclined plane.

A body is pushed up on a rough inclined plane making an angle 30^@ to the horizontal. If its time of ascent on the plane is half the time of its descent, find coefficient of friction between the body and the incined plane.

A body of mass m slides down an inclined plane making an angle of 45^(@) with the horizontal. If the coefficient of friction between the body and the plane be 0.3, the acceleration of the body is approximately equal to :
