The material point moves according to the law x = 6-t. what is this movement? find a) the initial coordinate of the point (at time t0 = 0) b) coordinate at time t1 = 3 s c) find the modulus and direction of the velocity. draw the trajectory of the point. build graphs of speed versus time v (t) and coordinates versus time x (t)

According to the law of motion, it can be seen that the motion is uniform rectilinear (the trajectory is straight, the body moves along the OX axis).
a) initial coordinate: Xo = 6m
b) at time t1 = 3c: X = 3m
c) Since the speed is negative, the body moves against the OX axis. V = -1m / s
The graph of dependence V (t) is a straight line, of the type y = m.
The graph of dependence X (t) is a linear function of the form: y = kx + b
