Question

A force of 75 N is exerted on a 45 kg sofa, and the sofa is moved 5 m. How much work is done moving the sofa?

Answer 1

Answer:

375 joule

Step-by-step-explanation:

Force exerted on 45 kg of sofa = 75N

Displacement happened = 5m

We know that,

Work Done = $\sf Force \times Displacement$

Work Done = 75kg× 5N

Work Done = 375 Joule.

Additional information:

In science, the work happens when some displacement happens. Either you lift an object to a certain height or displaces an object to a certain distance.

Scientifically, we define work done as the magnitude of the force multiplied by the distance moved by the object in the duration of applied force.

Potential Energy: The energy acquired by a body due to its change in position and shape is called potential energy.

Law of conservation of energy says that energy can neither be created nor destroyed, it can only be transformed into one form to another. The total energy, before and after the transformation always remains constant.

Answer 2

Answer:

Given :-

• A force of 75 N is exerted on a 45 kg sofa, and the sofa is moved is 5 m.

Find Out :-

• Work done by the sofa.

Formula Required :-

$\small{\boxed{\underline{\underline{\bf{Work\: Done\: =\: Force \times Displacement}}}}}$

Solution :-

Given in the question :

➡ Force = 75 N

➡ Mass = 45 kg

➡ Displacement = 5 m

According to the question,

↦ W = Fd

↦ W = 75 × 5

➦ W = 375 J

∴ The work done by the sofa is 375 J.
