Regarding the Earth's motion (and the motion of every other planet),
there suddenly wouldn't be any centripetal force to curve the Earth's
path. So the Earth would sail off in a straight line, in the direction it
was moving at the instant when the sun's gravity disappeared.
Although everything would become very dark, you wouldn't feel
anything different. Even now, as we follow the curved orbit around
the sun, the direction of the Earth's motion only changes by about
one degree per day, so we don't feel it.
Throw it sideways and try to make it spin around but it needs to be thrown high up then it should kinda glide down
This question involves the concept of the conservation of energy.
(a) The child's speed halfway will be "12.13 m/s".
(b) The child's speed three-fourth way will be "14.86 m/s".
(a)
Using the <em>law of conservation of energy</em>:
Potential Energy Lost = Kinetic Energy Gained

where,
v = speed = ?
g = acceleration due to gravity = 9.81 m/s²
h = height lost = halfway = height/2 = 15 m/2 = 7.5 m
Therefore,

<u>v = 12.13 m/s</u>
<u />
(b)
Using the <em>law of conservation of energy</em>:
Potential Energy Lost = Kinetic Energy Gained

where,
v = speed = ?
g = acceleration due to gravity = 9.81 m/s²
h = height lost = three-fourth way down = 
Therefore,

<u>v = 14.86 m/s</u>
<u />

The attached picture shows the <em>law of conservation of energy</em>.
..... equal to the force from the engine pushing the car forward.
That's why the car is not accelerating. The horizontal forces on it
are balanced.
Answer:
It is not impossible to answer the question, my apologies for “discrediting” the answer it would have to be Venus, the outer planet most similar to earth.
Explanation:
Venus is very similar to earth, as many studies, research, factual intellectual based concepts - the size, shape, surface gravity, average density, mass, average days of 24 hours, season changes similar to earth, and tilted axis. As well as similar climate make Venus the most accurate answer.
Hope this helps! Thank you for your time.
