Two solid uniforms disks are attached to each other so they rotate together as shown above. The smaller disk has a mass of 5.00 kg and a radius of 1.00 m. The larger disk has a mass of 15.0 kg and a radius of 2.00 m. A 25.0 kg box is hung by a rope that wraps around the larger disk. A force, F1 is applied to the smaller disk so that the box is raised upward with a linear acceleration of 3.00 m/s2. A. What is the tension on the rope?
B. What is the angular acceleration of the smaller disk?
C. What must be the force F1 to produce this acceleration?

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
