The speed of movement of a given body can be set by the formula:
V = V0 + a * t, where, according to the condition of the problem, V0 (the speed with which the body was thrown up) = 19.6 m / s; a (body acceleration) = -g (gravitational acceleration, equally slow motion) = – 9.8 m / s2.
The speed of the body when reaching the maximum height will be equal to zero.
0 = V – g * t and t = V / g.
Let’s perform the calculation:
t = 19.6 / 9.8 = 2 s.
Answer: The lifting time of a given body will be 2 seconds.
