To calculate the skidding time, we use the formula $t = \frac{v}{a}$, where $v$ is the initial velocity (20 m/s) and $a$ is the deceleration. Given deceleration is 0.5 g, where g is approximately 9.8 m/s$^2$, so $a = 0.5 \times 9.8 = 4.9$ m/s$^2$. Plugging the values in, $t = \frac{20}{4.9} \approx 4$ seconds.
