Question

A flight attendant pulls her 66 N flight bag a distance of 318 m along a level airport floor at a constant velocity. The force she exerts is 43 N at an angle of 52 above the horizontal.Find the work she does on the flight bag.

Answer 1

To find the work done, multiply the horizontal component of the force by the distance the bag moves in that direction.

Step-by-step explanation:

The work done on an object is equal to the force applied to the object multiplied by the distance the object moves in the direction of the force. In this case, the flight attendant exerts a force of 43 N at an angle of 52° above the horizontal. To find the work done, we need to determine the horizontal component of the force and the distance the bag moves in that direction.

The horizontal component of the force can be found by multiplying the force by the cosine of the angle between the force and the horizontal direction:

Fhorizontal = 43 N * cos(52°)

Next, we need to find the distance the bag moves in the horizontal direction. Since the bag is pulled along a constant velocity, the distance it moves is given as 318 m.

Finally, we can calculate the work done:

work = Fhorizontal * distance
