Question

2 Two identical stones, each of mass 300 g, are dropped from a height of 4 m - one above the equator and other above the north pole. Assuming all conditions to be identical, compare the time taken by stones to reach ground. Justify your answer.​

Answer 1

Answer:

"This can be quite simply derived from the equations of motion s=ut+1/2at2

v-u=at

v2-u2=2as

since initial velocity of both are zero s=1/2at2"

Answer 2

Answer:

Given that mean =14 and median =15

We know that mode=3median−2mean

⟹mode=3(15)−2(14)=45−2
