Question

Rex decides to launch a priceless vase into the air at a 90-degree angle. The initial velocity vase is +7.0 m/s. Dylan claims that the vase would achieve a higher height if it were launched at a 45-degree a Dylan correct? A. Dylan is correct because a 45-degree launch angle results in the largest vertical range B. Dylan is correct because larger launch angles result in a smaller vertical range. C. Dylan is incorrect because a 90-degree and 45-degree launch angle result in the same range. D. Dylan is incorrect because a 90-degree launch angle results in the largest vertical range​

Answer 1

Answer:

D. Dylan is incorrect because a 90-degree launch angle results in the largest vertical range​

Explanation:

Projectile is the motion of an object thrown into space. When an object is thrown into space, the only force which acts on it is the acceleration due to gravity.

An object thrown into space would reach maximum height (vertical range) if it is launched at an angle of 90 degrees. For maximum horizontal range, the object needs to be launched at an angle of 45 degrees.

Therefore Dylan is incorrect because a 90-degree launch angle results in the largest vertical range​

Answer 2

The correct statement is

D. Dylan is incorrect because a 90-degree launch angle results in the largest vertical range​

Information regarding projectile:

It is the object motion that should be thrown into space. At the time when the object is thrown into space, the only force that should act on it represent the acceleration because of gravity.

Since object thrown into space should have to reach maximum height in the case when it is launched the 90 degrees angle. Due to the above reasons, option D is considered.
