Suppose a brick has a mass of 4.50 kg. What is the brick's weight at the surface of the Earth

mg =4.5 x 9.8 = ...(N)

Well, if we're talking about the surface of the Earth, then the brick's weight would be crushing... I mean, I'm sorry, it would be the force exerted on it due to gravity. The weight (W) can be calculated using the formula: W = m * g, where m is the mass of the brick and g is the acceleration due to gravity. On Earth's surface, the average value of g is approximately 9.8 m/s². So, if the brick has a mass of 4.50 kg, its weight would be approximately 44.1 Newtons. That's one heavy brick! Better watch out for any falling bricks! Keep your head on a swivel!

To determine the brick's weight at the surface of the Earth, we need to use the formula:

Weight = mass x acceleration due to gravity

The acceleration due to gravity on the surface of the Earth is approximately 9.8 m/s^2.

Weight = 4.50 kg x 9.8 m/s^2

Weight = 44.1 N (rounded to the nearest tenth)

Therefore, the brick's weight at the surface of the Earth is 44.1 Newtons.

To calculate the weight of an object, we need to use the formula:

Weight = Mass x Acceleration due to gravity

The acceleration due to gravity on the surface of the Earth is approximately 9.8 m/s². Therefore,

Weight = 4.50 kg x 9.8 m/s²

To find the weight, multiply the mass of the brick (4.50 kg) by the acceleration due to gravity (9.8 m/s²).

Weight = 44.1 N

So, the weight of the brick at the surface of the Earth is 44.1 Newtons.
