Which of the following would not be taken into consideration when describing the quality of a sound

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
