I just finished this question on my test and got it right. 85 is your answer.

False. A Red Giant evolves from a main sequence star after it commences
Helium fusion and undergoes a great expansion; in the case of our Sun
it would expand to encompass Earth's orbit. Thus, it would have
approximately the same mass (a small amount being expelled in the helium
flash), and vastly greater volume, equating to vastly lower density.
You're welcome :)

Answer:
Because the velocity v (As a Vector ) is going opposite direction ( -X axis ) .
We will first record its mass and then its volume by measuring its dimensions
then divide mass by volume and will get density of regular solid
