#27. Are there any large external forces on this system? [What are some of the small ones?] How might you use this effect?
#55. There is an adequate hint in the problem statement. Notice, however, that the two sentances in the hint say effectively the same thing.
#67. For additional thought: if you cannot determine the speed of A from the information given, what would you have to know to determine that speed? You should find two and only two equations for this situation.
#68. There is no excited state of the deuteron. It is either in its ground state or it breaks up. Is the collision elastic or inelastic?
#7, 19. The definitions required are in section 11-2. The physics and mathematics of angular acceleration is just like that of linear acceleration, only the names have changed. The correspondance is r ~ theta, v ~ omega, and a ~ alpha.
#44. How many radians are travelled in going all the way around a circle? For parts (c) and (d), what would you have done if the questions had been about linear distance, velocity, and acceleration?
#59. Kinetic energy is discussed in section 11-6. The speed 200 pi rad/sec is obviously an angular speed.
