A student exerts a force of 50 N on a lever at a distance 0.4 m from its axis of rotation. The student pulls at an angle that is ...

Two masses are balanced on the scale pictured above. If the bar connecting the two masses is horizontal and massless, what is th ...

The torque that produces the angular acceleration of the particle is = rF, and is directed out of the page. From the linear vers ...

A record of mass M and radius R is free to rotate around an axis through its center, O. A tangential force F is applied to the r ...

The masses in the figure above are initially held at rest and are then released. If the mass of the pulley is M, what is the ang ...
