The body is thrown vertically upward at a speed of 25 m / s. What is the speed after 2 seconds.
| May 13, 2021 | education
To calculate the speed of the thrown body in 2 seconds, apply the formula: V = V0 + a * t = V0 – g * t.
Values of variables and constants: V0 – speed at the moment of throw (V0 = 25 m / s); g – acceleration due to gravity (g ≈ 10 m / s2); t – elapsed time (t = 2 s).
Calculation: V = V0 – g * t = 25 – 10 * 2 = 5 m / s.
Answer: After 2 seconds, the thrown body will have a speed of 5 m / s.
