Book A with a mass of 1.00 kg is placed on a horizontal table. Book B with a mass of 0.500 kg is placed on top of book A. What is the magnitude of the normal force exerted on book A by the table?

Respuesta :

Answer:

Explanation:

N = mg = (1.00 + 0.500)(9.81) = 14.7 N

The magnitude of the normal force exerted on book A by the table is 14.7 N

Forces

From the question, we are to determine the magnitude of the normal force.

The normal force ca be calculated by using the formula

[tex]F_{n} = mg[/tex]

Where [tex]F_{n}[/tex] is the normal force

m is the mass

and g is the gravitational field strength ( g = 9.8 m/s²)

The mass will be addition of the masses since Book B is placed on top of the book.

Thus,

m = 1.00 kg + 0.500 kg = 1.50 kg

Then,

[tex]F_{n} = 1.5 \times 9.8[/tex]

[tex]F_{n} = 14.7 \ N[/tex]

Hence, the magnitude of the normal force exerted on book A by the table is 14.7 N
