Hand written solution required

Consider a block of 5 kg is placed on an inclined plane at an angle of 300 to the horizontal and a constant force is applied horizontal to the ground as shown in the figure. The inclined plane has a rough surface with a static coefficient of friction us = 0.3 and a kinetic coefficient of friction uk = 0.2 between the plane and the block (a) Find the range of values of the applied force needed for the block to remain in limiting equilibrium on the inclined plane. (b) If the applied force is 100 N and it causes the block to move a distance of 20 m up the incline, calculate the net work done on the block and hence the final velocity of the block. F - 5 kg 300
