Question

1. A 10 kg object experiences a horizontal force which causes it
to accelerate at 5 m/s2, moving it a distance of 20 m,
horizontally. How much work is done by the force?​

Answer 1

Answer:

1000 Nm

Explanation:

Force experienced by the object = mass of object * acceleration

= 10kg * 5 m/s²

= 10 * 5 N {kg*m/s² = N}

= 50N

Workdone = force * distance

= 50N * 20 m

= 1000 Nm

Answer 2

Answer :

›»› The work is done by the force is 1000 J.

Given :

• A 10 kg object experiences a horizontal force which causes it to accelerate at 5 m/s², moving it a distance of 20 m, horizontally.

To Calculate :

• How much work is done by the force?

Calculation :

• Mass (m) = 10 kg
• Acceleration (a) = 5 m/s²
• Distance (d) = 20 m
• Work done = ?

Here in this question we have to find the work is done by the force. So, firstly we have to find force experienced by a object, after that we will find work done of object on the basis of conditions given above.

From second law of Newton

→ Force = ma

→ Force = 10 * 5

→ Force = 50 N

Now,

As we know that

→ Work done = F * d

→ Work done = 50 * 20

→ Work done = 1000 J

║Hence, the work is done by the force is 1000 J.║
