It then undergoes a change, and the new rotational inertia is calculated to be a third of the original value. What is the new rotational period of the star?
- • Problem 3.22 The potential energy between the atoms of an hydrogen molecule can be modelled by means of the Morse potential -2(r – ra) (r V (r) = V exp 2 еxp where Vo = 7 × 10 12 erg, ) = 8 x 10-º cm and a = 5 x 10-º em.A uniform rod of length 1.20 m and mass 2.00 kg is free to rotate about a frictionless axle through one end. From the horizontal position, the rod is released from rest. A small piece of putty of mass 0.500 kg is suspended from the pivot by a string of negligible mass and length 0.800 m, as shown in the figure below. The putty sticks to the rod on contact. Determine the amount of mechanical energy dissipated in the collision. 1.20 m 0.800 m puttyThe apparatus below is a massless wheel of radius that is mounted to a frictionless axle. A small, dense piece of clay with mass is glued to edge of the wheel as shown. Another mass hangs from a massless string that is wrapped around the wheel. We can assume the string is inextensible and does not slip, and the system is in a uniform gravitational field. In terms of the rotation angle of the wheel, write down the total potential energy of the system of both masses. Take note of any constraints that you use to write this as a 1D problem.

Which reaches the bottom first, and what is the speed of each there?The system is made up of the 1-m, 7.1-kg uniform rod AB and the two uniform disks (each of 0.17 m radius and 1.9 kg mass). If the system is released from rest when = 63°, determine the total external work done to this system when rod AB has just become horizontal. Assume the disks roll without slipping. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper Sl unit. Take g = 9.81 m/s².
