Answer:
the super train is not completely within the tunnel.
Explanation:
From the given information:
The proper length = 1200 ft
The super train speed = 0.99c
By applying the concept of length contraction, the contracted length of the super-train can be determined by using the formula:
L = 169.3 ft
≅ 169 ft
Thus, the contracted length is 169 ft more than the proper length of the tunnel L' 50 ft.
As such, the super train is not completely within the tunnel.

<span>There are approximately 1600 meters/mile. Estimating a five second per mile delay in the arrival of the sound, then the estimate of the speed of sound is (a)1600/5 or 320 meters/sec or (B) 320 x 60 sec x 60 min / 1600 m/mile or about 720 miles/hour.</span>
