Question

1. A boy pulls a cart through a distance of 50 m by applying
a force of 20 N. How much work is done by the boy?​

Answer 1

Answer:-

Your Answer Is 1000 J.

Explanation:-

Given:-

• Force (f) = 20 N.

• Distance i.e. displacement (as the the cart is pulled in straight line) (d) = 50 m.

To Find:-

• The work done by the boy.

Formula Used:-

• ↦ Work Done = Force × Displacement.

Solution:-

By Using The Formula,

↦ Work Done = f × d.

↦ Work Done = 20N × 50m.

↦ Work Done = 1000 Nm.

↦ Work Done = 1000 J.

Therefore The Work Done By The Boy Is 1000 J.

Answer 2

Aɴsᴡᴇʀ :

• Work done (W) $\leadsto \textsf{\textbf{\red{1000 J}}}$

Gɪᴠᴇɴ :

• Force (F) = 20 N

• Displacement i.e, distance (S) = 50 m

Tᴏ Fɪɴᴅ :

• Work done (W).

Fᴏʀᴍᴜʟᴀ Usᴇᴅ :

• $\boxed{\sf{W = F\times S}}$

Sᴏʟᴜᴛɪᴏɴ :

$\leadsto\sf{W = F\times S}$

$\leadsto \sf{W = 20\times 50 \:Nm}$

$\leadsto \sf{W = 1000 J}$
