Two astronauts are working on the lunar surface to install a new telescope. The acceleration due to gravity on the moon is only

nydimaria [60]

Answer:

Its velocity and acceleration are both nonzero.

Explanation:

The path of the wrench is trajectory while the acceleration due to Moon's gravity is acting on it.

As the velocity follows the path, as soon as it reaches maximum height, the vertical component of velocity is zero but the horizontal component is still there, constant.

This model shows a ball being shot from the cannon. Which of these statements accurately describes the energy of the cannonball?

Fudgin [204]

The potential energy of the model will be the greatest at point C while it will be the least at point E. Option B and D are correct.

<h3>What is potential energy?</h3>

The potential energy of an object is due to its position. It can be given as the formula,

$U = mgh$

Where,

$U$ - potential energy

$m$ - mass

$g$ - gravitation acceleration

$h$ - height

From the formula since the mass and gravitation acceleration is constant, the potential energy of the model will depend upon the height only.

The potential energy will be greatest at point C because the relative position of the ball is the highest from the earth.

The potential energy will be lowest at point E because the height of the ball is the least in this position.

Therefore, the potential energy of the model will be the greatest at point C while it will be the least at point E.
