Question

Времч 10 секунд начальная скорость 0 путь равен 25 м найти конечную скорость

Answer 1

1)S=v0+at²/2, v0=0, S=at²/2, a=2S/t², a=2×25 м / (10 с)²=0,5 м/c². 2) v=v0+at, v0=0, v=at, v=0,5 м/c² × 10 c= 5 м/c.

Answer 2

Problem Statement

You are given the following information: - Initial velocity (v0) = 0 m/s - Distance (x) = 25 m

You need to find the final velocity (v) after 10 seconds.

Solution

To find the final velocity, we can use the equation of motion:

v = v0 + at

where: - v is the final velocity - v0 is the initial velocity - a is the acceleration - t is the time

In this case, the initial velocity (v0) is 0 m/s, and the time (t) is 10 seconds. We need to find the acceleration (a) to calculate the final velocity.

To find the acceleration, we can use the equation:

x = x0 + v0t + (1/2)at^2

where: - x is the distance - x0 is the initial position (which is 0 in this case) - v0 is the initial velocity - t is the time - a is the acceleration

In this case, the distance (x) is 25 m, the initial position (x0) is 0 m, the initial velocity (v0) is 0 m/s, and the time (t) is 10 seconds. We can rearrange the equation to solve for acceleration (a):

a = 2(x - x0) / t^2

Substituting the given values:

a = 2(25 - 0) / (10^2) a = 2(25) / 100 a = 50 / 100 a = 0.5 m/s^2

Now that we have the acceleration, we can substitute it back into the equation of motion to find the final velocity:

v = v0 + at v = 0 + (0.5)(10) v = 0 + 5 v = 5 m/s

Therefore, the final velocity after 10 seconds is 5 m/s.
