Question

in 10 seconds, a car changes velocity by δv = +7 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: Identify given values

$\Delta V = + 7\ m/s$, $t=10\ s$

Step2: Apply acceleration formula

$a=\frac{\Delta V}{t}=\frac{7}{10}=0.7\ m/s^{2}$

Answer:

$+0.7$
