An applied force of 6 Newtons acts in the direction of motion of a block of mass 9 Kg, with the mass being pulled across the floor against a frictional force of .6 Newtons. Assume that the block moved the distance 'y' in this process.

* What is the net force on the object?
* How much work does the net force do on the object?
* How much work does the applied force do on the object?
* What is the work done by the frictional force on the object?
* If the object had initial velocity 6 m/s, and if the force was applied for 3 seconds, then what is its acceleration and by how much did the velocity of the object therefore increase?
* What was its change in kinetic energy?
* How is this change related to the work done by the applied force and the frictional force?
* How is this change related to the work done by the net force?

Solution Preview

An applied force of 6 Newtons acts in the direction of motion of a block of mass 9 Kg, with the mass being pulled across the floor against a frictional force of .6 Newtons.

* What is the net force on the object?
6N - 0.6N = 5.4 N

* How much work does the net force do on the object?
Work = Force x Distance = 5.4 * y
where y is the distance through which the block was dragged across the floor

* How much ...
