1. The hollow tube is pivoted about at point 0, rotating in the vertical plane with a constant clockwise angular velocity of 3 rad/sec. If a 230 g plug is sliding in the tube towards 0 with a constant speed of 30 mm/sec relative to the tube when the position 30 degrees is passed and the plug is at 300 mm from O • find the normal force on the plug find the friction force on the plug Make sure to clearly state the direction the forces act in.

Expert Solution
Step 1

Newton's Second Law of Motion

According to Newton's Second Law of motion, the rate of change of momentum of an object is directly proportional to the net external force acting on the object. Mathematically it is given as

∑i=1nFi=ma

The LHS is the net external force acting on an object of mass m causing an acceleration a.
