Question

in 5 seconds, a car goes from traveling at 32 m/s to 24 m/s. what is the acceleration of the car? a = ? $\frac{m}{s^{2}}$ enter the sign (+ or -) and the magnitude. remember: a = $\frac{delta v}{t}$

Explanation:

Step1: Calculate change in velocity

$\Delta v=v_f - v_i=24 - 32=- 8$ m/s

Step2: Calculate acceleration

$a=\frac{\Delta v}{t}=\frac{-8}{5}=-1.6$ m/s²

Answer:

-1.6
