Question

A box having mass 5 kg is move from point A to B which is 10 m in distance. calculate the amount of work done. If the acceleration produce during the motion is 2 m/s².​

Answer 1

Required Answer:-

We have:

• Mass of the body = 5 kg
• Distance covered = 10 m
• Accl. produce during the motion = 2 m/s²

To FinD:

• The amount of work done by the body?

Step-by-step Explanation:

By using Newton's 2nd law, Finding the force applied on the body. We have the Mass and the accleration of the body.

Force applied:

⇒ F = ma

⇒ F = 5 kg × 2 m/s²

⇒ F = 10 kg m/s² / 10 N

Now we got the force applied on the body. We know that, Work done by the body is the product of force applied and displacement covered$.$

Amount of work done:

⇒ W = Fs

⇒ W = 10 N × 10 m

⇒ W = 100 Nm / 100 Joules

Hence:-

• The amount of work done by the body by covering 10 m displacement is 100 Joules.

Answer 2

Answer:

Given :-

➙ Mass of the body = 5 kg

➙ Distance covered = 10 m

➙ Accl. produce during the motion = 2 m/s²

To find :-

Amount of work done.

SoluTion :-

First we shall find force applied by using newton second law.

$\huge \bf \: F\: = ma$

➙ F = 5 × 2

➙ F = 10 N

➣ Force applied = 10 Newton

Now,

Finding work done

$\huge \bf \: W \: = fs$

➙ W = 10 × 10

➙ W = 100 J

➣ Work done = 100 Joule

Hence, work done = 100 Joule
