A 5.0-kilogram box is sliding across a level floor. The box is acted upon by a force of 27 newtons east and a frictional force of 17 newtons west. What is the magnitude of the acceleration of the box?

Answer :

Answer:

The magnitude of the acceleration of the box is 2 m/s².

Explanation:

Given:

Mass of the box, [tex]m=5.0[/tex] kg

Force acting towards east, [tex]F=27[/tex] N

Frictional force acting towards west, [tex]f=17[/tex] N

Let the acceleration be [tex]a[/tex] m/s².

Now, net force acting on the box towards east is given as:

[tex]F_{net}=F-f=27-17=10\textrm{ N}[/tex]

From Newton's second law of motion,

[tex]F_{net}=ma\\10=5.0\times a\\a=\frac{10}{5.0}=2\textrm{ }m/s^2[/tex]

Therefore, the magnitude of the acceleration of the box is 2 m/s².

Further explanation

Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.

[tex]\large {\boxed {F = ma }[/tex]

F = Force ( Newton )

m = Object's Mass ( kg )

a = Acceleration ( m )

Let us now tackle the problem !

Given:

mass of box = m = 5.0 kg

force = F = 27 N

frictional force = f = 17 N

Asked:

acceleration of the box = a = ?

Solution:

We will use Newton's Law of Motion to solve this problem as follows:

[tex]\Sigma F = ma[/tex]

[tex]F - f = ma[/tex]

[tex]27 - 17 = 5.0a[/tex]

[tex]10 = 5.0a[/tex]

[tex]a = 10 \div 5.0[/tex]

[tex]a= 2.0 \texttt{ m/s}^2[/tex]

[tex]\texttt{ }[/tex]

Conclusion:

The magnitude of the acceleration of the box is 2.0 m/s²
