the two ms cancel each other out and ur left with s
t=12s

Ability to memorize and regurgitate information on tests is the skill that can’t help a person to thrive today in this modern 21st century.
Answer: Option D
<u>Explanation:</u>
Thriving in this modern 21st century is not as easy as it used to be in the early 20th and 19th centuries. So there is a need to develop skills like implementing one's knowledge to real-world structures which will sure help a person to understand and explore more.
Statement B also will sure be helpful to survive in modern society and a person can also improve his/her critical thinking, problem solving and other skills to thrive through this century.

Answer:
<em>The crate should be released 3,080 m in front of the target</em>
Explanation:
<u>Horizontal Launch
</u>
When an object is thrown horizontally with a speed v from a height of h, it describes a curved path ruled by gravity until it hits the ground.
The range or maximum horizontal distance traveled by the object can be calculated as follows:

The airplane drops a crate horizontally from a height of h= 2,750 m when flying at v=130 m/s. The range or maximum horizontal distance the crate reaches is:

Operating:

d = 3,080 m
The crate should be released 3,080 m in front of the target
