Answer:
a) Deceleration = 201.76 m/s^2
b) Distance traveled = 197.68 m
Explanation:
Initial Speed = 632 mi/h
Initial Speed (in meters/second) = (632 * 1.609 * 1000) / (60 * 60) = 282.4 m/s
Time to decelerate = 1.4 seconds
a) Change in speed = Acceleration * time
-282.4 = Acceleration * 1.4
Acceleration = -201.76 m/s^2
Deceleration = 201.76 m/s^2
b) Distance traveled = average speed * time
average speed = 282.4 / 2 = 141.2 m/s
Distance traveled = 141.2 * 1.4
Distance traveled = 197.68 m

The correct answer is the Black Market.
The Black Market refers to the informal (and sometimes formal) system of trading of illegal goods by merchants and dealers of products such a weapons, drugs, and good that have been banned by countries. This can also apply to informal marketplaces in countries with sanctions placed upon them get goods that formal treaties are blocking the people from accessing.
