Question

A man is carrying the load of 25N and he covers the distance of 2500cm. Calculate the work done by the person.​

Answer 1

Answer:

d= 2500/100= 25m

f=25N

Work done= f×d

= 25×25= 625joules

Answer 2

Answer :

The work done by the person is 625 joules ✔

Step-by-step explanation :

Given that,

A man is carrying load of 25N and he covers distance of 2500cm.

Here, the force and the displacement is given, we need to find the work done by the person.

Step 1 :

Convert the unit of ‘cm’ into ‘m’ :

Since, 1 m = 100cm.

→ 2500cm = 25 m

Step 2 :

Calculate the work done :

Work done by the person is given by :

→ f × d

• f (force) = 25N
• d (displacement) = 25m.

So,

→ 25 × 25

→ 625 joules.

Note behind :

• The work done is measured by the unit Joule.
• The unit of the force and the displacement must be in N (Newton) and m (metres)
