The coordinate of a body moving rectilinearly and uniformly is determined by the equation x = 5-3t

The coordinate of a body moving rectilinearly and uniformly is determined by the equation x = 5-3t. Determine the initial coordinate, speed and direction of movement of the body. please write and given if …

x (t) = 5 – 3 * t.

x0 -?

V -?

With uniform rectilinear motion, the dependence of the coordinates of the body on time х (t) has the form: х (t) = х0 + Vх * t, where х0 is the initial coordinate of the body, Vх is the projection of the speed of movement on the coordinate axis ОХ.

For the dependence х (t) = 5 – 3 * t, the coordinate of the body at the beginning of the movement was х0 = 3 m, the projection of the velocity Vх = – 3 m / s.

The “-” sign in the velocity projection shows that the body is moving in the opposite direction to the direction of the OX coordinate axis, that is, the body coordinate will decrease.

Answer: the initial coordinate of the body is х0 = 3 m, the body moves in the opposite direction of the ОХ axis at a speed of V = 3 m / s.
