The anthropic principle suggests that in some sense we are observing a special kind of universe; if the universe were different, we could never have come to exist. comment on how this fits with the copernican tradition described in exercise 29.19.

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:
