Question

Determine the amount of work done by the applied force when a 87 N force is applied to move a 15 kg object a horizontal

distance of 4.5 meters at a constant speed.

Answer 1

Mass doesn't matter on amount of work done .We can calculate amount of work done through Force and Displacement

• Force=87N
• Displacement=4.5m

`\boxed{\sf W=Fd}`

• W denotes to work done
• F denotes to force
• d denotes to displacement

`\\ \sf\longmapsto Work\:Done=87(4.5)`

`\\ \sf\longmapsto Work\:done=391.5J`

Answer 2

391.5 J

Step-by-step explanation:

The amount of work done can be calculated using the formula:

• W = F║d
• where the force is parallel to the displacement

Looking at the formula, we can see that the mass of the object does not affect the work done on it.

Substitute the force applied and the displacement of the object into the equation.

• W = (87 N)(4.5 m)
• W = 391.5 J

The amount of work done on the object is 391.5 J in order to move it 4.5 meters with an applied force of 87 Newtons.
