Question

A body of mass 35kg is placed on a horizontal surface, the coefficient of friction
between the surfaces is 0.5. Find the applied force if the net force is 10N.
(A) 200N
(B) 150N
(C) 185N
(D) 250N​

Answer 1

Explanation:

we learned how to determine the net force if the magnitudes of all the individual forces are known. In this lesson, we will learn how to determine the acceleration of an object if the magnitudes of all the individual forces are known. The three major equations that will be useful are the equation for net force

Answer 2

Net force=force applied-static friction force (1)

Static friction force = coefficient of friction*mg

m = 35kg
g = 10

Static friction force = 0.5*35*10

Static friction force = 175N

From (1)

10 = force applied - 175N

Force applied is 185N
