Answer 1

Question :


Calculate the amount of work done in drawing a bucket of water weighing  15 kg from a well of depth 30m.​

___________________________________________

Answer :

Given, mass = 15 (m) kg
Acceleration due to gravity (g) = 9.8 m/s²
Height (h) = 20 m

W =mgh
= 15 × 9.8 × 30
= 4410 joules

Answer 2

Given:

• The weight of the bucket = 15 Kg
• The height of the well = 30 m

To Find:

• The amount of work done in drawing the bucket.

Solution:

The formula to find the work done is given by,

⇒ W = m×g×h → {equation 1}

Where "m" is the mass, "g" is the acceleration due to gravity(g = 9.8 m/$s^2$), and "h" is the height.

On substituting the values in equation 1 we get,

⇒ W = 15×9.8×30 {multiplying the terms}

⇒ W = 4410 J

∴ The amount of work done in drawing the bucket = 4410 J
