A block of mass2 kg is dragged up an inclined plane. The plane is inclined at an angle of 45degrees to the horizontal. The coefficient of kinetic friction between the block and the plane is 0.5.
Part A
What force is needed to drag the block up the plane at a constant speed?
Part B
What force is needed to accelerate the block up the plane at a rate of 5 meters per second squared?
Part C
If the force acting in Part-B drags the block by 10m, how much work does it do to the block?
Part D
What is the work done by gravity on the block as it is dragged up by 10m?
Part E
What is the work done by the frictional force on the block as it is dragged up by 10m?
