Task data: V1 (speed of the taken vehicle before braking) = 36 km / h (in SI V = 10 m / s); t (braking time) = 10 s.
We express the acceleration modulus of the vehicle taken from the formula for calculating the speed during slow motion: V2 = V1 – a * t = 0, whence a = V1 / t.
Let’s calculate: a = 10/10 = 1 m / s2.
Answer: The acceleration module of the taken vehicle was 1 m / s2.
