The ball is thrown vertically upward at a speed of 10m / s. At what height will it be in 2 s?
| August 6, 2021 | education
V0 = 10 m / s – initial speed t = 2 s – ball movement time h -? h = V0 * t – g * t ^ 2/2, sign “-” because the movement is free, acceleration and speed are directed in opposite directions g = 9.8 m / s ^ 2 h = 10 * 2 – 9.8 * 2 ^ 2/2 = 0.4 m
Answer: h = 0.4 m
