The aircraft increased in 12 seconds. speed from 240 km / h to 360 km / h What is the movement of the aircraft during this time?

The aircraft increased in 12 seconds. speed from 240 km / h to 360 km / h What is the movement of the aircraft during this time? with what acceleration did the plane move?

Given:
t = 12s
Vo = 240 km / h
V = 360 km / h
Find: a-? S -?
Decision:
at = V – Vo = 360 – 240 = 120 (km / h) = 33.33 (m / s)
a = 33.33: 12 = 2.78 (m / s ^ 2)
S = Vo * t + (a * t ^ 2) / 2 = 1000.16 (m)
Answer: a = 33.33 m / s ^ 2; S = 1000.16 m.
