The body moves against the ox axis, the modulus of speed is 36 The initial coordinate is 20 m, find the position of the body in 4 with which the path traveled by the body is equal.
Task data: V0 (constant speed module) = 36 m / s; x0 (start coordinate) = 20 m; t (duration of movement) = 4 s.
1) Coordinate of the body after 4 seconds: x (4) = x0 – V * t = 20 – 36 * 4 = -124 m.
2) The path covered by the body: S = x (0) – x (4) = 20 – 36 * 0 – (-124) = 144 m.
Answer: In 4 seconds, the body covered a path of 144 m, and its coordinate became equal to -124 m.
