The initial speed of the body is equal to 2m / s after 4s the speed has become equal to 8m / s

The initial speed of the body is equal to 2m / s after 4s the speed has become equal to 8m / s, calculate the acceleration of the body.

Task data: Vн (initial speed) = 2 m / s; t (duration of body movement) = 4 s; Vk (final speed) = 8 m / s.

You can calculate the acceleration of a given body using the formula: Vk = Vn + a * t, whence a = (Vk – Vn) / t.

Let’s calculate: a = (8 – 2) / 4 = 6/4 = 1.5 m / s2.

Answer: The given body moved with an acceleration of 1.5 m / s2.
