Please show the work :(What is the estimated force applied to the box if the acceleration is .40 m/s2? force (N) acceleration (m/s2)
10 .20

? .40

20N

Explanation:

Given parameters:

        Force(N)     Acceleration(m/s²)  

            10                   0.2

           ?                      0.4

Unknown:

The force applied when the acceleration is 0.4m/s²

Solution:

From newton's second law of motion;

 Force = mass x acceleration

 Since we are using the same box, let us find the mass of the box;

      Force  = mass x acceleration

         10 = mass x 0.2

            mass =  = 50kg

Now,

 The force in the second instance will be;

      Force  = 50 x 0.4  = 20N

the correct answer is:

a. formation of precipitation
