Q. What is the tangential acceleration of a bug on the rim of a 11.0 in. diameter disk if the disk moves from rest to an angular speed of 76 rev/min in 5.0 s?
Q. The motion of peg P is constrained by the lemniscate curved slot in OB and by the slotted arm OA.
If OA rotates counterclockwise with an angular velocity of dot theta = (3t^{3/2}); rm rad/s, where t is in seconds, determine the magnitude of the velocity of peg P at theta = 30^circ. When t = 0, theta = 0^circ.
Let the masses of blocks A and B be 4.0 kg and 2.0 kg, in that order, the moment of inertia of the wheel about its axis be 0.400 kg*m^2, and the radius of the wheel be 0.140 m. Find the linear accelerations of block A if there is no slipping between ..
The lines in a grating are uniformly spaced at 1520nm. Analyse the angular separation of the second order bright fringes between light of wavelength 603nm and 615.4 nm. Reply in units of mrad.
You work for a moving company and are given the job of moving two crates (masses are 130kg and 280kg) held together by a rope attached between the two. You pull on a rope attached to the larger crate giving the system the acceleration of 0.29m/s2. Wh..
A soccer ball with a mass of 448g bounces off the crossbar of a goal and is deflected upward at an angle of 56.2° with respect to horizontal. Immediately after deflection, the kinetic energy of the ball is 47.70 J. What are the vertical and horizo..
