A machinist turns the power on to a grinding wheel, which is at rest at time t = 0.00 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 25 rad/s.
 
  The wheel is run at that angular velocity for 37 s and then power is shut off. The wheel decelerates uniformly at 1.5 rad/s2 until the wheel stops. In this situation, the time interval of angular deceleration (slowing down) is closest to: A) 17 s
  B) 15 s
  C) 19 s
  D) 21 s
  E) 23 s

Question 2

The wave is observed in such experiments as the electron double-slit experiment is
 
  A) a traveling disturbance in a large collection of electrons or other sub-atomic particles.
  B) due to oscillations of the various sub-atomic force fields such as the strong force field.
  C) a wave in an electromagnetic field.
  D) a wave in a matter field.
  E) due to the impact of sub-atomic particles, such as neutrinos, that randomly hit and deflect the moving electron.
