If an object is moving with a constant velocity, then by definition it has zero acceleration. So there is no net force acting on the object. The total work done on the object is thus 0 (that's not to say that there isn't work done by individual forces on the object, but the sum is 0 ).
To answer the question the antenna would probably burn up in the atmosphere. I have no idea how to get that thing on Earth if it's by itself. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

Adding both distances together, you get a total of 1800 miles. With the total travel time of 4 hours, you divide the distance traveled by the time it took. so 1800/4=450 mph
Answer:
The correct answer is A.
Objects in free fall accelerate due to <u>gravity</u>.
Explanation:
Momentum can help an object to keep its state of motion at a constant velocity when no external force is applied. It can never accelerate the object.
According to the laws of motion, we know that acceleration is produced in a body only when a Force is applied in the direction of motion of body.
During a free fall, only the force of gravity is acting on an object and that too in the direction of its motion. Hence, the acceleration produced in a free falling object is due to gravity.
