Question

Please explain why all of their escape speeds from the moon are equal.

I'm confused as to why they're equal because using the formula for escape velocity, shouldn't the escape speed be the largest for the third mass, followed by the second then the first mass?

Question 2 We have three objects with the masses mi = 1 kg, m2 = 2 kg, and m3 = 3 kg. Your answer is correct. (a) Rank them according to their escape speeds from the Moon. Indicate the ranking by moving the labels into the boxes, with the greatest escape speed at the top left. Use side-by- side boxes for any ties, in numeric order. Click here to start

Answer 1

The escape velocity of moon is, v= 12g Here g is the acceleration due to gravity of moon GM g=72 So the escape velocity is, From the above formula the escape velocity does not depends on the mass of the object So, the given mass has same escape velocities. The ranking is, m = m = m;
