A student proposes to measure the gravitational constant G by suspending two spherical objects from the ceiling of a tall cathedral and measuring the deflection of the cables from the vertical. Draw a free-body diagram of one of the objects. (Do this on paper. Your instructor may ask you to turn...

A block of mass 10.0 kg is pushed up against a wall by a force P that makes a 50.0° angle with the horizontal as shown in Figure P5.13. The coefficient of static friction between the block and the wall is 0.253. Determine the possible values for the magnitude of P that allow the block to remain...
