How long does it take for a body to acquire a speed of 36 km / h, moving with an acceleration of 0.2 m / s ^ 2?

V0 = 0 m / s.
V = 36 km / h = 10 m / s.
a = 0.2 m / s ^ 2.
t -?
The acceleration of the body, and is determined by the formula: a = (V – V0) / t, where V, V0 are the final and initial speed of movement, respectively, t is the time during which the speed changes.
t = (V – V0) / a.
t = (10 m / s – 0 m / s) / 0.2 m / s ^ 2 = 50 s.
Answer: the body will acquire speed in time t = 50 s.
