Task data: V1 (the speed with which the given body moved) = 18 km / h (in SI V1 = 5 m / s); t (braking time) = 4 s.

The acceleration with which the given body moved in slow motion is determined by the formula: a = (V2 – V1) / t = (0 -V1) / t = -V1 / t.

Let’s perform the calculation: a = -5 / 4 = -1.25 m / s2.

Answer: The acceleration of a given body was -1.25 m / s2.
