Ball a, of mass m_a, is connected to ball b, of mass m_b, by a massless rod of length L. The two vertical dashed lines in the figure, one through each ball.
What is the torque (TD) about axis D due to F? (D is the point located at a distance d from the origin and making an angle phi with the x axis.)
A circular disk of radius 0.010 m rotates with a constant angular speed of 5.0 rev/s. What is the acceleration of a point on the angle of the disk?
The one dimensional parity operator (pie) is defined by attached. in other wards (phi) changes x into -x everywhere in the function
A top is spinning counterclockwise as shown in the figure. It is also moving to the right with a linear speed v. What is the direction of the angular velocity?
