Question

In the metric system, force is measured in Newtons (N). Work is measured in joules (J). A joule is defined in the system as a newton-meter (Nm). If you applied a force of 200 Newtons to lift a box 2.20 meters above the floor, how much work would you be doing?

0.011 J
90.9 J
440 J
44,000 J

Answer 1

Answer:

Work = 440 J

Explanation:

Here we need to calculate the work done, The formula to calculate the work done is given by,

• Work done = Force × displacement

Given that: If you applied a force of 200 Newtons to lift a box 2.20 meters above the floor.

• So, Force = 200 Newtons
• Displacement = 2.20 meters

Substitute the required values in the above formula,

• Work = 200 N × 2.20m
• Work = 440 J

Hence, the required work done is 440 J
