A cat reaches its terminal velocity of 60 mph within 5 stories of freefall. For comparison, an average person's maximum recorded terminal velocity is 120 mph.

Terminal velocity describes the velocity at which drag force from the air ( air resistance) becomes equal to the force ( gravitiational pull) from the weight of an object, and thus the object no longer accelerates and consequently velocity remains constant. The greater an object's cross-sectional area and the less its mass, the lower the terminal velocity and the sooner it's reached.

In a vacuum mass would not matter at all - Astronaut David Scott dropped a feather and a hammer during Apollo 15 on the moon. I They both landed at the same time since the moon has virtually no atmosphere. However, on earth, the resistance of air will have a more profound effect on something with lesser mass.

Drag is the only thing that matters in terminal velocity. Wasn't it Galileo that rolled to similar spheres with different weights down the streets to prove the point that gravity affects all bodies the same? This may be wrong, but if it is someone will be able to answer it correctly and concisely.

i cant watch this video wanting new friends r7

You can only eleimnate the weigh of the object from that eqation when there is no air resistance. when you add in air resistance to the falling object equation, then terminal velocity is determined ONLY with weight or mass into the equation. without it, you wont know what the actual terminal velocity could be
