Question
a = \frac{change\\ in\\ velocity}{time}
an object traveling at 10 m/s comes to a complete stop in 2 seconds. what is the objects acceleration?
200 m/s²
5 m/s²
-5 m/s²
Step1: Identificar valores iniciales y finales
La velocidad inicial $v_0 = 10$ m/s y la velocidad final $v_f=0$ m/s, y el tiempo $t = 2$ s.
Step2: Aplicar fórmula de aceleración
La fórmula de aceleración es $a=\frac{v_f - v_0}{t}$. Sustituyendo los valores: $a=\frac{0 - 10}{2}=\frac{- 10}{2}=-5$ m/s².
