The net force is what remains of the pull when we subtract the friction force:
[tex]F = 64-36 = 28N[/tex]
Now, use the law
[tex]F=ma[/tex]
and solve it for the acceleration
[tex]a = \dfrac{F}{m}[/tex]
to get the result:
[tex]a = \dfrac{28}{14}=2[/tex]
Answer:
2 m/s²
Step-by-step explanation:
F = applied force in the horizontal direction = 64 N
f = frictional force acting between the box and the floor = 36 N
m = mass of the box = 14 kg
a = acceleration of the box = ?
Force equation along the horizontal direction is given as
F - f = ma
Inserting the values
64 - 36 = 14 a
28 = 14 a
a = [tex]\frac{28}{14}[/tex]
a = 2 m/s²
