The body began to move along the X-axis at a constant speed of 6 m / s from a point with a coordinate X0 = -7m. How many seconds will the body coordinate be equal to 5m?
Since the body moves with constant speed, the motion is uniform, therefore, the coordinate equation will take the form:
x = x0 + V * t
V * t = x-x0
t = (x-x0) / V = 12/6 = 2s
Answer: 2 sec
