Question

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 1

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

A) The box with a mass of 2 kg

Step-by-step 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

`a =(F)/(m)`

A) The box with a mass of 2kg

F = 8 N

`a =(8)/(2)`

a = 4 m/s2

B) The box with the mass of 4kg

`a =(8)/(4)`

a = 2 m/s2

C) The box with a mass of 6kg

`a =(8)/(6)`

a = 1.33 m/s2

D) The box with a mass of 8kg

`a =(8)/(8)`

a = 1 m/s2
