A ball weighing 100 g falls from a height of 10 m. What is its velocity at the moment of falling?

Ball weight 100 grams (or 0.1 kg). It falls without initial speed from a height of h = 10 m.

The formula by which the speed of a body is determined at the moment of falling to the ground is as follows:

V = √2gh, where g is the acceleration of gravity (let’s take it as 9.8 m / s2), h is the height (in meters) from which the body falls.

Thus, the speed of the ball at the moment of falling:

V = √2 * 9.8 * 10 = 14 m / s.

Answer: the speed of the ball at the moment of falling to the ground was 14 m / s.
