Question

A woman performs 360 J of work by lifting her husband a distance of 0.4 m. How much force did she apply?

a) 900 N
b) 1,440 N
c) 400 N
d) 360 N

Answer 1

The woman applied a force of 900 N.

Step-by-step explanation:

To find the force applied by the woman, we can use the formula:

Work (W) = Force (F) x Distance (d)

Given that the work done is 360 J and the distance is 0.4 m, we can rearrange the formula to solve for force:

Force (F) = Work (W) / Distance (d)

Plugging in the values, we get:

Force (F) = 360 J / 0.4 m = 900 N

Therefore, the woman applied a force of 900 N.
