Question

the frictional force of air on a body of mass 0.25 kg falling with acceleration 9.2 is​

Answer 1

Answer:

0.15 N

Explanation:

Given the frictional force of air on a body of mass 0.25 kg falling with acceleration 9.2 is​

Acceleration due to gravity is 9.8 m/s^2. Now acceleration due to frictional force of a falling body is reduced to 9.2 m/s^2  

So change in acceleration will be 9.8 – 9.2 = 0.6 m/s^2

Now friction due to air will be equal to m x a

                                           = 0.25 x 0.6

                                           = 0.15 N

So Frictional force on body due to air is 0.15 N
