Massachusetts Institute of Technology - Physics Department Physics - 8.01 Assignment #6 October 22, 1999. It is strongly recommended that you read about a subject before it is covered in lectures. Lecture Date Material Covered Reading Mon 10/25 Exam #2 Handout of 10/18 #19 Wed 10/27 Rotating Rigid Bodies - Moment of Inertia Page 296–309 Parallel Axis and Perpendicular Axis Theorem Rotational Kinetic Energy - Flywheels Handout of 10/27 Neutron Stars - Pulsars Take Notes #20 Fri 10/29 Angular Momentum - Torques Page 310–317, 327–329 Conservation of Angular Momentum Page 336 (Ex. 7), Page 338 (Ex. 9) Spinning Neutron Stars - Stellar Collapse Take Notes Due Monday, Nov 1, before 4 PM in 4-339B. 6.1 Serious Car Accident – page 291, problem 13 6.2 Colliding Bobs – page 292, problem 23 6.3 Sliding on Ice John and his friend, Nancy, sit motionless on sleds on frictionless ice. John slides a 10 kg block across the ice to Nancy at 3 m/sec relative to his sled (i.e. after the block is released, the relative velocity of the block relative to his sled is 3 m/sec). Nancy catches it and slides it back to John at the same speed of 3 m/sec relative to her own sled. John and his sled (without the 10 kg block) together have a mass of 100 kg, and Nancy and her sled together have a mass of 80 kg. a) What is the speed of John’s sled and what the speed of the block after John releases the block? b) What is the speed of Nancy’s sled immediately after she catches the block?
