Question

the acceleration due to gravity on the moon's surface is one-sixth that on earth. if a person can jump 2.5m high on Earth, how high can the same person jump on the moon, assuming this person starts off with the same velocity ?

Answer 1

first you do 1/6 of earths gravity

1/6*9.8=1.63

then multiply 1.63to 2.5=4.08

thats the height

Answer 2

4.0833333333333333333333333333333m at least it should be...

Answer 3
