Question

Определите скорость свободно падающего тела через 3 с после начала падения.

Answer 1

30 м/с.
Вообще формула V(x) = V(0) + at.
V(0) = 0. Так как его отпустили, а не бросили.
a = g = 10 м/с.
t = 3 c.
И всё под формулу. V(x)= 0 + 10*3 = 30

Answer 2

Calculation of the Speed of a Freely Falling Object

To determine the speed of a freely falling object after 3 seconds of falling, we can use the equation for the speed of an object in free fall:

v = gt

Where: - v is the speed of the object - g is the acceleration due to gravity (approximately 9.8 m/s^2 on Earth) - t is the time in seconds

Substituting the given values into the equation, we have:

v = (9.8 m/s^2) * (3 s) = 29.4 m/s

Therefore, the speed of the freely falling object after 3 seconds of falling is 29.4 m/s.

Please note that this calculation assumes no air resistance and that the object is falling near the surface of the Earth.
