Question

The Burj Khalifa is the tallest building in the world having a height of 828 m. Imagine a coin dropped on top of this building and a man is passing and his head was hit by the falling coin. Would the coin be as damaging as a stone that travels a hundred meters per second? A raindrop falls from about 2500 feet. With the gravitational force pulling the water downward, it will gain a very high velocity as it hits the ground. Why is a raindrop not as fatal as a speeding bullet?​

Answer 1

When you drop something in air, it does not accelerate forever. ... As the object gains velocity there comes a time when the force of the air resistance is enough to balance the force of gravity, so the acceleration stops and the raindrop attains terminal velocity.
