To determine the acceleration value of a given tram, we will use the formula: a = (Vk – Vn) / t.

Variables: Vк – the final speed of the tram (Vк = 0 m / s, the tram stopped); Vн – speed before braking (Vн = 12 m / s); t is the duration of inhibition (t = 1 min = 60 s).

Calculation: a = (Vk – Vn) / t = (0 – 12) / 60 = -0.2 m / s2.

Answer: The acceleration of this tram during braking was -0.2 m / s2.
