Question

if you drop a banana, how fast is it going after 2 seconds? 5 m/s 10 m/s 20 m/s 30 m/s

Explanation:

Step1: Identify the acceleration formula

The formula for velocity $v = v_0+at$. When an object is dropped, the initial - velocity $v_0 = 0\ m/s$ and the acceleration due to gravity $a = 10\ m/s^2$ (approximate value near the Earth's surface).

Step2: Substitute values into the formula

We know $v_0 = 0\ m/s$, $a = 10\ m/s^2$, and $t = 2\ s$. Substituting into $v=v_0 + at$, we get $v=0+10\times2$.

Step3: Calculate the velocity

$v = 20\ m/s$.

Answer:

$20\ m/s$
