Unformatted text preview: Massachusetts Institute of Technology - Physics Department Physics - 8.01 Assignment #4 October 6, 1999. It is strongly recommended that you read about a subject before it is covered in lectures. Lecture Date Material Covered Reading #13 Fri 10/8 Potential Energy - watch PIVoT Page 184 – 194 Energy Considerations to derive SHM - watch PIVoT Page 387 – 389 #14 Wed 10/13 Escape Velocities - Bound and Unbound Orbits - PIVoT Page 211 – 228 Circular Orbits (elliptical orbits will be discussed later Page 194 – 201 in the course). Various Forms of Energy - Power #15 Fri 10/15 Momentum - Conservation of Momentum - watch PIVoT Page 113 – 114 Center of Mass - watch PIVoT Page 245 – 261 Due Friday, Oct 15, before 4 PM in 4-339B. Solutions will be posted on the Web Sat, Oct 16. 4.1 Air drag on very small drops. Watch PIVoT under resistive force . We release an oil drop of radius r in air. The density of the oil is 700 kg / m 3 . C 1 and C 2 for 1 atmosphere air at 20 ◦ C are 3 . 1 × 10- 4 (kg / m) / sec and 0 . 85kg / m 3 , respectively. How small should the oil drop be so that the drag force is dominated by the linear term in the speed (in lectures we called this Regime I ). In this regime, the terminal velocity is mg/C 1 r . [ m is the mass of the drop]....
