The block of ice (temperature 0°C) shown in Figure P9.53 is drawn over a level surface lubricated by a layer of water 0.10 mm thick. Determine the magnitude of the force F needed to pull the block with a constant speed of 0.50 m/s. At 0°C, the viscosity of water has the value n = 1.79 x 10-8 N. s/m2. -1.20 m 0.800 m 0.10 mm The block of ice (temperature 0°C) shown in Figure P9.53 is drawn over a level surface lubricated by a layer of water 0.10 mm thick.
