Question: figure 818 shows a person pushing a block of mass...

Question details

8.13 Exercise Problems Problem 8.1 Figure 8.18 shows a person pushing a block of mass m on a surface that makes an angle 0 with the horizon- tal. The coefficient of kinetic friction between the block and s the inclined surface is A. y Fig. 8.18 Problem 8.1 t If the person is applying a force with constant magnitude P and in a direction parallel to the incline, show that the acceleration of the block in the direction of motion can be expressed as: g (Al cos 0 t sin 0)
