From a high steep cliff, a stone begins to fall freely. What speed will it have in 3 seconds

From a high steep cliff, a stone begins to fall freely. What speed will it have in 3 seconds after the start of the fall. Air resistance neglect.

Given:

t = 3 seconds – time interval;

g = 10 meters per second squared – acceleration due to gravity (constant near the surface of the earth).

It is required to determine v (meter per second) – the speed of the stone after a time interval t.

According to the condition of the problem, the stone falls freely, that is, without initial speed. In addition, we do not take into account the force of resistance, which means that the stone will move only under the influence of gravity. Then:

v = g * t = 10 * 3 = 30 meters per second.

Answer: the speed of the stone in 3 seconds will be equal to 30 meters per second.
