2. A 15-lb block rests on a horizontal surface. In order to start the block sliding, a horizontal force, F, of 4.5 lb must be applied. What is the coefficient of friction between the block and the surface? Show your calculation. - see Fig 5-8 on pg 101 F4 7 Sled test 3. At what angle, 0, would the surface in question 2 need to be inclined so that the block would just begin to slide? Show your calculation. - see Fig 5-8 on pg 101 777 Inclined plane 2.
