Question

Камень брошен вертикально вверх со скоростью 10 м/с. Определите его время движения.(Подробно)

Answer 1

Vo=10 м/с    to=? 
===
v=vo-g*t 
v - скорость в верхней точке v=0
t - время подъема
t=(vo-v)/g=(10-0)/10=1 c
Время подъема равно времени падения
to=2*t=2 c
============================

Answer 2

Calculating Time of Flight for a Stone Thrown Vertically Upward

To calculate the time of flight for a stone thrown vertically upward with a velocity of 10 m/s, we can use the following steps:

1. Identify the Relevant Equation: - The time of flight for an object thrown vertically upward can be calculated using the following equation: ``` v = u + at ``` where: - v = final velocity (0 m/s at the peak of the motion) - u = initial velocity (10 m/s in this case) - a = acceleration due to gravity (-9.81 m/s^2, assuming downward direction as negative) - t = time of flight

2. Calculate the Time of Flight: - Using the equation above, we can rearrange it to solve for time: ``` t = (v - u) / a ``` Substituting the given values: ``` t = (0 - 10) / (-9.81) ``` ``` t ≈ 1.02 seconds ```

So, the time of flight for the stone thrown vertically upward with a velocity of 10 m/s is approximately 1.02 seconds.
