Question

Using a a horizontal force of 200 Newton we intend to move a wooden cabinet across a floor at a constant velocity what is the frictional force that will be exerted on the cabinet

Answer 1

Answer:

Explanation:

                         

                     

since the object is moving with the constant velocity so accelaration must be zero as a=v-u/t

so 200-f=ma

⇒ 200=f

Answer 2

Answer:

As according to Newton's 3rd law of motion:-

Action is always equal to the reaction we r moving the wodden cabinet forward that the reaction is occured in the opposite direction. So, frictional force will be also 200 N.
