Initially, the speed of the moving body is 30 m / s, the final speed is 90 m / s. travel time 0.4 parts of an hour

Initially, the speed of the moving body is 30 m / s, the final speed is 90 m / s. travel time 0.4 parts of an hour. determine acceleration.

Initial data: V1 (initial speed of a moving body) = 30 m / s; V2 (final speed) = 90 m / s; t (body travel time) = 0.4 h (1440 s).

You can determine the acceleration of a moving body from the formula: V2 = V1 + a * t, whence a = (V2 – V1) / t.

Let’s make a calculation: a = (90 – 30) / 1440 = 60/1440 = 0.0417 m / s2.

Answer: The body was moving with an acceleration of 0.0417 m / s2.
