The motor ship moving uniformly accelerated from a state of rest with an acceleration of 0.10 m / s ^ 2, a speed of 18 km / h. How long has this speed been reached? What path has been covered during this time?

V = V0 + at = .V0 = 0 => V = at t = v / a = 5 / 0.1 = 50c
S = at ^ 2/2 = 125m km / h we preliminarily translate into m / s: 18 * 1000/3600 = 5m / s
