A wooden crate of mass 25 kg is sitting on a horizontal cement floor. Then, one end of a horizontal pulley is attached to the crate. The rope in the pulley loops around twice, so that the pulley provides a force 4 times bigger than the tension in the rope. Now the rope is given a continuous tension, T, until the crate has been dragged a distance of 6.2 m across the floor. The static and kinetic coefficients of friction between the wood and the cement are 0.56 and 0.35, respectively. How many newtons of tension, T, were required in the the pulley rope, for the crate to start to move?
