To find the value of the speed of the specified body after 4 seconds of free fall, you must use the formula: V = a * t = g * t.
Constants and variables: g – acceleration of gravity, acceleration of the specified body (g = 9.81 m / s2); t is the duration of the fall (t = 4 s).
Calculation: V = g * t = 9.81 * 4 = 39.24 m / s.
Answer: After 4 seconds, the speed of the specified body will be equal to 39.24 m / s.
