Question

Find the work WWW done by the 18-newton force. Use two significant figures in your answer. Express your answer in joules.

Answer 1

The work done by the 18-newton force cannot be calculated without knowing the distance.

Step-by-step explanation:

The work done by a force can be calculated using the formula:

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

Given that the force is 18 newtons, the work can be found by multiplying the force by the distance over which the force is applied. However, the distance is not provided in the question, so it is not possible to calculate the work accurately without that information. Therefore, an exact value for the work cannot be determined.

Answer 2

W = (18) d

W = 18 d

Now, this is the work done by 18 N force in Joules. Here, d is the value of displacement that occurs due to the force.

If we assume a distance of 1 m, then work done will be:

W = (18 N)(1 m)

W = 18 J

Step-by-step explanation:

Work is said to be done when a force is applied to an object. And the object displaced by some distance as a result of the applied force. Hence, the formula for the work done is given as follows:

W = F d Cosθ

where,

W = Work Done

F = Force Applied

d = displacement

θ = Angle between force and displacement

We are given a force of 18 N. So, in order to find the work done we first assume that the force and displacement are in same direction (θ = 0°).

W = (18) d

W = 18 d

Now, this is the work done by 18 N force in Joules. Here, d is the value of displacement that occurs due to the force.

If we assume a distance of 1 m, then work done will be:

W = (18 N)(1 m)

W = 18 J
