The body was thrown vertically upward at a speed of 20 m / s. To what height will it rise?
| January 19, 2021 | education
To find the height that the taken body can reach, we apply the formula: h = S = (Vk ^ 2 – Vn2 ^) / 2a = (Vn ^ 2 – 0 ^ 2) / 2g.
Values of variables and constants: Vн – vertical throw speed (Vн = 20 m / s); g – acceleration due to gravity (g ≈ 10 m / s2).
Calculation: h = Vн2 / 2g = 202 / (2 * 10) = 20 m.
Answer: The taken body had to rise to a height of 20 m.
