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.
True or false setting a heavy suitcase down on the ground requires you to do negative work on it?
False. Setting a heavy suitcase down on the ground does not require you to do negative work on it. Work is only done when you apply a force to an object and move it over a distance in the direction of the force applied. Simply placing the suitcase on the ground does not involve any work being done.

Suitcase can hold up to 66litres how heavy in kilograms is this?
