The body is thrown vertically upward with an initial speed of 14.7 m / s. How long does it take to rise to the maximum height, neglect the air resistance.
To find the duration of lifting the thrown body to the maximum height, we use the formula: Vk = 0 = Vn + a * t = Vn – g * t, whence we express: t = Vn / g.
Variables and constants: Vн – speed of throwing upwards (Vн = 14.7 m / s); g – acceleration due to gravity (g ≈ 9.8 m / s2).
Calculation: t = Vн / g = 14.7 / 9.8 = 1.5 s.
Answer: The ascent of the thrown body to the maximum height lasted 1.5 s.
