Question

a porter can carry 40 bricks at time. if the weight of each brick is 10 N ,find his power if he caries up to 70 m and in 50 second
answer = 560 W

Answer 1

Given :

• No. of bricks = 40
• Weight of each brick = 10N
• Displacement = 70 m
• Time = 50 sec

To Find :

• Find His Power

Answer :

• 560 watt

Using Formula :

• Work = Force × Displacement

• Power = $\sf \frac{Work}{Time}$

Solution :

$\sf \longrightarrow$ No. of bricks = 40

• Total Force = 40 × 10 N = 400 N

$\sf \longrightarrow$ Now,

$\sf \longrightarrow$ Displacement = 70 m

$\sf \longrightarrow$ Time = 50 sec

• Work = F (Force) × d (displacement)
• Work = 400 × 70
• Work = 28000

Now,

• Power = $\sf \frac{Work}{Time }$

• power = $\sf \frac{28000}{50}$

• Power = $\sf \frac{\cancel{28000}^{\: \: 560}}{\cancel{50}}$

• $\sf \red \bigstar \green{\underline{\underline{Power = 560 \: \: watt}}}$

Hence , Power = 560 watt

I hope it helps you ❤️✔️
