Two ice skaters, lilly and john, face each other while at rest, and then push against each other's hands. the mass of john is twice that of lilly. how do their speeds compare after they push off? lilly's speed is one-fourth of john's speed. lilly's speed is the same as john's speed. lilly's speed is two times john's speed. lilly's speed is four times john's speed. lilly's speed is one-half of john's speed.

Lilly's speed is two times John's speed.

Explanation:

m = Mass

a = Acceleration

t = Time taken

u = Initial velocity

v = Final velocity

The force they apply on each other will be equal

Hence, Lilly's speed is two times John's speed.

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

it doesn't. it was imagined up in the middle ages.
