Question

Тело движется равноускоренно с ускорением 3 м/с2, имея начальную скорость 5м/с. Путь пройденный телом, 24 м. Чему равно конечная скорость тела?

Answer 1

S=V^2-V0^2/2*a
V=sqrt(V0^2+2*a*S)=sqrt(25+2*3*24)=13 м/с

Answer 2

Calculation of Final Velocity

To determine the final velocity of an object moving with constant acceleration, we can use the following equation:

v^2 = v0^2 + 2aΔx

Where: - v is the final velocity - v0 is the initial velocity - a is the acceleration - Δx is the displacement or distance traveled

In this case, the object is moving with an acceleration of 3 m/s^2, an initial velocity of 5 m/s, and has traveled a distance of 24 m.

Using the equation above, we can substitute the given values:

v^2 = (5 m/s)^2 + 2 * 3 m/s^2 * 24 m

Simplifying the equation:

v^2 = 25 m^2/s^2 + 144 m^2/s^2

v^2 = 169 m^2/s^2

Taking the square root of both sides to solve for v:

v = √(169 m^2/s^2)

v = 13 m/s

Therefore, the final velocity of the object is 13 m/s.
