Answer:
move at constant velocity.
Explanation:
Newton's first law (also known as law of inertia) states that:
"when the net force acting on an object is zero, the object will keep its state of rest or if it is moving, it will continue moving at constant velocity".
In the case of the probe, friction in deep space is negligible, therefore when the engine is shut down, there are no more forces acting on the probe: the net force therefore will be zero, so the probe will move at constant velocity.
in case you dont want to read the answer is B
Force and acceleration have directions. They're vectors.
Speed and temperature don't. They're not.
The same number of electron shells, the atomic number is given to each individual element, same as the atomic mass, and properties have nothing to do with groups
Mass = (2*KE) / v²
∴ the answer is 200/49
