Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.
