Newton S Laws Of Motion

Step 1: Understanding the forces.
The applied force is 100 N, and the frictional force is
given by , where is the coefficient of friction and is the normal force.
For a horizontal surface, the normal force is equal to the weight of the object, . The frictional force is:
Step 2: Net force and acceleration.
The net force acting on the body is the applied force minus the frictional force: Now, using Newton's second law: Thus, the correct answer is
(C) 5.2 m/s
