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.

Suitcase can hold up to 66litres how heavy in kilograms is this?
66Kg You really cannot tell how much the suitcase can hold in mass. 66 litres is the volume of the suitcase. The answer would be 66 kg if you were carrying water, but I think the actual weight limit is going to be far less, otherwise the suitcase would be capable of carrying the weight of a typical teenager (145 lb)

Answer: there should be a button on your suitcase, if there is, then press it and push the lever then it will work and then you will be carrying your suitcase like you should, with your extendable handle.
