Переведи на английский: Материальная точка движется прямолинейно по закону x=t(t-3)(t-4) (где x  — расстояние от точки отсчета в метрах, t  — время в секундах, измеренное с начала движения). Найдите ее скорость (в м/с) в момент времени t  =  7 с

The material point moves in a straight line according to the equation \( x = t(t-3)(t-4) \) (where \( x \) is the distance from the reference point in meters and \( t \) is the time in seconds measured from the start of the motion). Find its velocity (in m/s) at the moment \( t = 7 \) seconds.

To find the velocity, we need to take the derivative of the position function \( x(t) \) with respect to time \( t \) to get the velocity function \( v(t) \).

Given:
\[ x = t(t-3)(t-4) \]

First, we expand the equation:
\[ x = t(t^2 - 4t + 3t + 12) \]
\[ x = t^3 - 7t^2 + 12t \]

Next, we differentiate \( x \) with respect to \( t \):
\[ v(t) = \frac{dx}{dt} = \frac{d}{dt}(t^3 - 7t^2 + 12t) \]
\[ v(t) = 3t^2 - 14t + 12 \]

Now, we substitute \( t = 7 \) into the velocity equation:
\[ v(7) = 3(7)^2 - 14(7) + 12 \]
\[ v(7) = 3(49) - 98 + 12 \]
\[ v(7) = 147 - 98 + 12 \]
\[ v(7) = 61 \]

Therefore, the velocity of the material point at the moment \( t = 7 \) seconds is \( \boxed{61 \, \text{m/s}} \).
