Question

Vo = 15 kм/ч V = 90 км/ч t = 1ч a-? ​

Answer 1

Ответ: 5,79*10⁻³м/с²

Объяснение:

Дано:

Vo = 15 kм/ч = 4,17м/с

V = 90 км/ч =25м/с

t = 1ч =3600с

-------------------

a-?

а=(V-Vo)/t=(25-4,17)/3600=5,79*10⁻³м/с²

Answer 2

To find the acceleration (a) when you have the initial velocity (Vo), final velocity (V), and time (t), you can use the following equation:

a = (V - Vo) / t

Given:

• Initial velocity (Vo) = 15 km/h
• Final velocity (V) = 90 km/h
• Time (t) = 1 hour

Now, plug these values into the equation:

a = (90 km/h - 15 km/h) / 1 hour

a = 75 km/h / 1 hour

a = 75 km/h²

So, the acceleration is 75 km/h².
