Aflight attendant pulls her 70 n flight bag a distance of 253 m along a level airport floor at a constant speed. the force she exerts is 40 n at an angle of 53° above the horizontal

a. find the work that she does on the flight bag
b. find the work done by the force of friction on the bag

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

If a simple machine reduces the strength of a force, what must be increased?
