Answer 1

Appropriate Question :

• A man weighting 600 N carries a load of 200 N on his head. If he climbs a height of 5m. Find the work done

Given

• Weigh of the man = 600 N
• Weight of the load = 200 N
• Height = 5 m

To Find

• Work Done

Solution

☯ Work = Force × Displacement

• Here the force will be equal to the sum of the mass of the man and the load

━━━━━━━━━━━━━━━━━━━━━━━━━

✭ Force :

➞ Total Force = Weight of man + Weight of Load

➞ Total Force = 600 + 200

➞ Total Force = 800 N

━━━━━━━━━━━━━━━━━━━━━━━━━

✭ According to the Question :

➞ Work = Force × Displacement

• Force = 800 N
• Displacement = 5 m

➞ Work = 800 × 5

➞ Work = 4000 J

∴ The work done by the man is 4000 J

Answer 2

Answer:

Given :-

• Weight of man = 600 N
• Weight of load = 200 N
• Height = 5 m

To Find :-

Work Done

Solution :-

Firstly we will find total weight

Total weight = Weight of man + Weight of Load

Total weight = 600 + 200

Total weight = 800 N

Now,

As we know that

Work Done = Force × Displacement

Work Done = 800 × 5

$\huge \fbox{Work Done = 4000 J}$
