Question

a stone is dropped from a certain height on earth and it takes 12s to reach the ground. if the same stone is dropped from the same height on moon, find the time that it will take to reach the surface of the moon​

Answer 1

Answer:

the object would fall for a longer time on moon approximately taking 2.45 times than the time taken on earth

Explanation

s=is the displacement

u=initial velocity

a=is the accleration due to gravity

t=is the time taken

we calculate it by using the formula s=ut+1/2at^2

Time take by stone on Earth=12 seconds

at Earth  a is equal to g

{(so time=(2*s/g)^0.5)FOR EARTH ON

but for moon

the gravity is less than Earths gravity which is 1/6times

so let a for moon=g/6

so[{ t=(12*s/g)^0.5}FOR MOON ONLY]

thus the object would fall for a longer time on moon approximately taking 2.45 times than the time taken on earth
