Question

Two stones of masses 3 Kg and 2 kg are dropped from a helicopter at the same time. Which one will reach the ground earlier? Justify your answer with suitable reason​

Answer 1

Answer:both will reach together.

Explanation:

Because Velocity does not depend on mass v=u+at.

Answer 2

both will reach the ground at the same time.

when a body is dropped from a certain height, it starts to fall downwards because of gravity. gravitational force acts on body by which earth attracts it towards her centre. acceleration acting on body due to gravity is g = 9.8 m/s² and this is approximately same for small distance compare to radius of earth.

now here two stones of masses 3kg and 2kg are dropped from a helicopter at the same time.

then, time taken to reach the ground by each of stones will be equal. because time doesn't depend on mass of stone.

I.e., h = 0 + 1/2 at² , here we see t only depends on acceleration (a = g) , height.

so, both will reach the ground at the same time.
