A brick weighing m = 4.0 kg lies on the table. What is the weight of a brick?

A brick weighing m = 4.0 kg lies on the table. What is the weight of a brick? The coefficient g should be taken equal to 10 N / kg.

The weight of the brick will be equal to the force of gravity and proportional to the acceleration of gravity and the mass of the brick itself.

Р = Fт = m * g, where m is the given mass of the brick (m = 4 kg), g is the acceleration of gravity (according to the condition, we take g = 10 N / kg = 10 m / s2).

Let’s make a calculation:

P = m * g = 4 * 10 = 40 N.

Answer: The weight of the brick is 40 N.
