D A top is a toy that is made to spin on its pointed cnd by pullingon a string wrapped around the body of the top. The string has a lengthof 64 cm and is wound around the top at a spot where its radius is 2.0 cm.*28.The thickness of the string is negligible. The top is initially at rest. Some-one pulls the free end of the string, thereby unwinding it and giving thetop an angular acceleration of +12 rad/s². What is the final angular velocityof the top when the string is completely unwound?

The final angular velocity is given by ω=ω02+2αθ

3. A telephone pole has been knocked over by the wind so that it makes an angle of 0 with the vertical. The wind has stopped blowing and the pole is to be cut down as shown. nail L cut Once the cut is across most of the thickness of the pole, the pole begins to tip over. As the pole tips, the bottom of the pole stays attached to the base by the remaining part of the pole that was not cut (but the torque from the base on the tipping pole is negligible). There is a nail (of negligible mass) on the pole located a distance x. The length of the pole from the cut to the top is L. Remember that the moment of inertia of a stick of mass m and length L about its end is mL?.
