| May 9, 2021 | education
V0 = 0 m / s.
g = 10 m / s2.
t = 5 s.
V -?
Only gravity acts on the body, so it moves uniformly with the acceleration of gravity g. We express the speed at uniformly accelerated motion V by the formula: V = V0 + g * t.
V = 0 m / s + 10 m / s2 * 5 s = 50 m / s.
Answer: the speed of the body will be V = 50 m / s.
