The bus approaches a stop at a speed of 36 km / h and stops in 10 seconds. Find acceleration

Vo = 36 km / h = 10 m / s. V = 0 m / s. t = 10 s. a -? According to the definition, the acceleration of the body a is determined by the formula: a = (V – Vо) / t. a = (0 m / s – 10 m / s) / 10 s = – 1 m / s ^ 2. The “-” sign means that the acceleration a is directed against the direction of motion, the body is decelerated.
Answer: the acceleration of the body is a = – 1 m / s ^ 2.
