This is very urgent please hurry!!?!!??!

Four boxes are sliding with a constant speed before each box experiences and unbalanced force of 8N. Which box would experience The greatest acceleration when the unbalanced force is applied?

A) The box with a mass of 2kg

B) The box with the mass of 4kg

C) The box with a mass of 6kg

D) The box with a mass of 8kg

Please hurry as fast as you can this is very urgent I really need this for a test please hurry!??!!!!!!!????!!

Answer:

The greatest acceleration when the unbalanced force is applied will be experienced in :

A) The box with a mass of 2 kg

Explanation:

According to second law of motion the external unbalanced force is directly proportional to rate of change of momentum.

F = (Final momentum - initial momentum)/time

or

Force is equal to the product of mass and acceleration

F = m x a

Here a= acceleration

m = mass of the object

If Force is constant then acceleration is inversely proportional to mass

[tex]a =\frac{F}{m}[/tex]

A) The box with a mass of 2kg

F = 8 N

[tex]a =\frac{8}{2}[/tex]

a = 4 m/s2

B) The box with the mass of 4kg

[tex]a =\frac{8}{4}[/tex]

a = 2 m/s2

C) The box with a mass of 6kg

[tex]a =\frac{8}{6}[/tex]

a = 1.33 m/s2

D) The box with a mass of 8kg

[tex]a =\frac{8}{8}[/tex]

a = 1 m/s2
