Question

Тіло кинули вертикально вгору зі швидкістю 6 м/с. На якій висоті воно буде через 0,4с?

Answer 1

2мм

Объяснение:

6 м/с-0.4с =

=2 мм/с

____________

Answer 2

Calculation of the Height

To determine the height at which the object will be after 0.4 seconds, we can use the equations of motion for vertical motion. The equation we will use is:

h = h0 + v0t + (1/2)gt^2

Where: - h is the final height - h0 is the initial height (in this case, 0 since the object is thrown vertically upwards) - v0 is the initial velocity (6 m/s upwards) - t is the time (0.4 seconds) - g is the acceleration due to gravity (approximately 9.8 m/s^2)

Plugging in the values, we can calculate the height:

h = 0 + (6 m/s)(0.4 s) + (1/2)(9.8 m/s^2)(0.4 s)^2

Simplifying the equation:

h = 0 + 2.4 m + 0.8 m

h = 3.2 m

Therefore, the object will be at a height of 3.2 meters after 0.4 seconds.
