Question

За 5 с скорость тела уменьшилась с 36км\ч до 27км\ч. Найти ускорение тела

Answer 1

$a=\frac{v-v_{0}}{t}=\frac{10-7,5}{5}=0,5$
(Скорость нужно перевести в метры в секунду)

Answer 2

$S= v_{0} t- \frac{a t^{2} }{2} = \frac{ v2^{2}- v1^{2} }{2a}$

Answer 3

Calculating the Acceleration of the Object

To calculate the acceleration of the object, we can use the formula:

Acceleration (a) = Change in velocity (Δv) / Time taken (Δt)

Given that the initial velocity (u) is 36 km/h and the final velocity (v) is 27 km/h, we can calculate the change in velocity (Δv) as:

Δv = v - u = 27 km/h - 36 km/h = -9 km/h

Now, we need to convert the change in velocity to a standard unit, such as m/s. To do this, we can use the conversion factor 1 km/h = 0.27778 m/s.

So, -9 km/h = -9 * 0.27778 m/s ≈ -2.5 m/s.

The time taken (Δt) is not provided in the question, so we cannot calculate the exact acceleration without this information. If you have the time taken, please provide it, and I can help you calculate the acceleration using the formula mentioned above.
