When you are sprinting with a suitcase when is work being done on your suitcase?

Technically, no; work is performed when lifting the suitcase, but not when holding it level. Work IS performed to accelerate the suitcase at the beginning of the sprint, when turning or climbing stairs, and to slow it down at the end; but carrying the suitcase at a constant velocity and constant height is not "work".

If A 130 N suitcase is dragged a distance of 250m at a constant speed A force of 60 N is exerted at an angle 40 degrees above the horizontal. a How much work is being done. b How much work is done?
The force which is responsible to make a drag through a distance of 250 m is the horizontal component of the force 60 N ie 60 cos 40 = 45.96 N Hence the work done = F s = 45.96 x 250 = 11490 joule. The usual formula for work done W = F s cos@ where @ is the angle between the force vector and the displacement vector. Here the weight of the suitcase is perpendicular to the displacement and so the value of cos 90 is zero and hence no work is done due to the weight of the suitcase.
What effect will the direction of the applied force to a book have on the amount of work being done?
The work being done will be increased if you pick it up instead of dragging it due to the friction.
How much force is done with the work being 10 and distance being 3?
Work is force times displacement (distance). Thus, about 3 work is being done. The unit depends on the unit of the work and distance. If the work unit is Joules, and the distance unit is meters, then the force unit would be Newtons.
Is work being done on an object in free fall?
Instead work on object, work is being done by the object during its free falling
If an object is being pushed but does not move is there any work being done on the object?
Yes Please

Which would be more work pulling a wheeled suitcase or carrying a suitcase?
pulling a wheeled suitcase. carrying a suitcase is not scientifically categorized as work.

How do you know work is being done?
work is being done when you use energy
Is work done if you push a car that has run out of gas?
Yes. The work is being done by whoever is pushing rather then the engine, but work is being done. Any time a force is applied through a distance, work is being done.
