I believe the correct answer would be A. The extraction of oil shale is detrimental to the environment mainly because the process of extraction requires large amounts of land. Lands are being excavated in order to locate areas which contains the oil. This is not good since it affects ecosystems and destroy habitats.
Recall that with constant acceleration,
where is the rocket's displacment, is its initial velocity, its final velocity, and is time. So
or just 2100 m if taking significant digits into account.
It would be 20 m/s because it is going vertically down
