In a clear, coherent, paragraph-length answer, explain why the speed of the apple half way between the release and the maximum h

Volgvan

Answer:

the speed of the apple half way between the release and the maximum height is not half the initial speed due to the acceleration due to gravity numerically equal to 9.81 m/s2. An acceleration in the direction of motion of a body will cause its velocity to increase, thus, this acceleration due to gravity increases the velocity of the apple so that it will be at its maximum speed before hitting the ground.

The value of this acceleration implies that there is an increase of 9.8 m/s in its speed for every one seconds of fall. This means that at 1 sec when it starts to fall, the speed will be 9.8 m/s. By two seconds it becomes 19.62 m/s. It is clear to see that the velocity halfway will be more than its initial velocity.

Select the correct answer. Physics is explicitly involved in studying which of these activities? A. the mixing of metals to form

geniusboy [140]

Answer: C. the motion of a spacecraft under gravitational influence.

Explanation:

A is Metallurgy, B is Biology, C is astro-physics, I am not sure what D is, but it's safe to say it's not physics, E, micro-biology, and the study of radiation. C is the only one involving physics.
