Question

in 5 seconds, a car goes from traveling at 6 m/s to 26 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 the change in velocity

$\Delta v=v_f - v_i$, where $v_f = 26\ m/s$ and $v_i = 6\ m/s$. So $\Delta v=26 - 6=20\ m/s$.

Step2: Use the acceleration formula

The formula for acceleration is $a=\frac{\Delta v}{t}$. Given $t = 5\ s$ and $\Delta v = 20\ m/s$. Then $a=\frac{20}{5}=4\ m/s^2$.

Answer:

$+ 4$
