Apendulum consists of a rod ab of length 2a and mass m, rotating about a horizontal axis through its one end b. let 6 denote the counterclockwise angle that the rod forms with the vertical line drawn down from point b. (17) (a) find the equation of rotation of the pendulum (b) what is the total mechanical energy of the pendulum, if the rod is initially held horizontal and then released? assume that the zero energy level of the gravita- tional energy goes through point b. (c) give all the initial conditions (specify the initial angle of rotation and angular velocity) which will ensure that the kinetic energy of the pendulum will always stay the same.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc

Afisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. it takes a time of 2.70 s for the boat to travel from its highest point to its lowest, a total distance of 0.700 m. the fisherman sees that the wave crests are spaced a horizontal distance of 6.50 m apart. a. how fast are the waves traveling? b. what is the amplitude a of each wave?
