Question

Calculate the weight of an object of mass 15kg on earth (take gravity=10m/s²)

Answer 1

weight=mass×g
=15×10
=150 newton

Answer 2

The weight of an object of mass 15kg on earth is 150 Newton

Given:

• Mass of an object = 15 kg
• g = 10 m/s²

To Find:

• weight of the object

Solution:

• W = mg
• W = Weight
• m = mass
• g = acceleration due to gravity

Use formula W = mg and substitute

m = 15 kg

g = 10 m/s²

W = 15(10)

W = 150 kg m/s²

W = 150 Newton

Hence,  the weight of an object of mass 15kg on earth is 150 Newton
