A block is given an initial push upwards on an inclined plane. The block slides up the plane to some point. It then reverses direction and slides down to the starting point. The time for the downward slide is exactly twice the time for the upward slide. The plane is inclined at an angle of 20.80 degrees above the horizontal. What is the coefficient of kinetic friction between the block and the plane?
