Question

Координата тела меняется с течение времени согласно по формуле х= 20+4t в единицах си с какой скоростью движется тело

Answer 1

Формула изменения координаты при равномерном движении:
x=x0+Vx*t
Сопоставляя эту формулу с формулой в условии и получаем что V=4

Answer 2

Formula for the Changing Coordinate of an Object

The formula for the changing coordinate of an object over time is given as x = 20 + 4t, where x represents the coordinate of the object and t represents time. This formula is in SI units.

Calculating the Velocity of the Object

To determine the velocity of the object, we need to find the derivative of the coordinate equation with respect to time. Taking the derivative of x = 20 + 4t gives us the velocity equation:

v = dx/dt = d(20 + 4t)/dt = 4.

Therefore, the object is moving with a constant velocity of 4 units per second.

Conclusion

The object is moving with a constant velocity of 4 units per second.
