Question

Скорость материальной точки изменяется по закону Vx равно 5-3t под действием силы 6 H какова масса точки . (ПОЖАЛУЙСТА ЧЕРЕЗ ДАНО)

Answer 1

Формула проекции скорости:
V(x) = V0(x) + a(x)*t
отсюда a=-3 м/с^2

F = ma
|m| = F / a = 6 / -3 = -2 = 2

Answer 2

Calculation of Mass of the Particle

To determine the mass of the particle, we need to analyze the given information about the velocity of the particle and the force acting on it.

The velocity of the particle is given by the equation Vx = 5 - 3t, where Vx represents the velocity of the particle along the x-axis and t represents time. The force acting on the particle is given as 6 H.

To find the mass of the particle, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.

In this case, the force acting on the particle is 6 H, and the acceleration can be calculated by taking the derivative of the velocity equation with respect to time. Differentiating Vx = 5 - 3t with respect to t, we get:

dVx/dt = -3

Since acceleration is the rate of change of velocity with respect to time, we have:

a = dVx/dt = -3

Now, we can use Newton's second law to find the mass of the particle:

F = ma

Substituting the given force and acceleration values, we have:

6 = m * (-3)

Simplifying the equation, we find:

m = -6 / -3 = 2

Therefore, the mass of the particle is 2 units.
