Question

a car accelerates from 5 m/s to 15 m/s in 2 s. what is its acceleration? a=(vf - vi)/t (1 point) 2 m/s^2 -2 m/s^2 5 m/s ^2 -5 m/s^2

Explanation:

Step1: Identify the values

$V_f = 15$ m/s, $V_i=5$ m/s, $t = 2$ s

Step2: Substitute values into formula

$a=\frac{V_f - V_i}{t}=\frac{15 - 5}{2}$

Step3: Calculate the acceleration

$a=\frac{10}{2}=5$ m/s²

Answer:

C. 5 m/s²
