EXAMPLE Given: A 25-kg block is subjected to the force F=100 N. The spring has a stiffness of k= 200 N/m and is unstretched when the block is at A. The contact surface is smooth. Find: Draw the free-body and kinetic diagrams of the block when s=0.4 m. Plan: 1) Define an inertial coordinate system. 2) Draw the block's free-body diagram, showing all external forces. 3) Draw the block's kinetic diagram, showing the inertial force vector in the proper direction.
