Question

The body moves along a straight axis in the negative direction of the OX axis. The coordinate of the body changes according to the law x = 1.5-1.2t. Find: initial coordinate, speed. Plot graphs of time-dependence, velocity-time, displacement-time?

Answer 1

Ответ:

1.5 m

-1.2 m/s

Объяснение:

Initial coordinate:

$\displaystyle x_0=x(0)=1.5-1.2*0=1.5$ m

Find the speed as a first derivate of coordinate:

$\displaystyle v(t)=\frac{d}{dt}x(t)=-1.2$ m/s
