Question

question 5 (1 point) if a car has a velocity of 40 m/s west and then comes to a stop (0 m/s) in 5 s, what is its acceleration in m/s²? a=(v_f - v_i)÷t the cars acceleration is ______ m/s² west. blank 1:

Explanation:

Step1: Identify given values

$V_i = 40\ m/s$, $V_f=0\ m/s$, $t = 5\ s$

Step2: Apply acceleration formula

$a=\frac{V_f - V_i}{t}=\frac{0 - 40}{5}$

Step3: Calculate the result

$a=\frac{- 40}{5}=-8\ m/s^2$

Answer:

$-8$
