1. Question: Find acceleration of a refrigerator 30s after a person begins pushing it at a force of 400 N, If the mass of the refrigerator is 10 kg.

   Answer:

   40 m/s²

   Explanation:

   Applying,

   F = ma…………….Equation 1

   Where F = Force applied to the refrigerator, m = mass of the refrigerator, a = acceleration of the refrigerator.

   make a the subject of the equation

   a = F/m………… Equation 2

   From the question,

   Given: F = 400 N, m = 10 kg

   Substitute these values into equation 2

   a = 400/10

   a = 40 m/s²
