Answer

Explanation:

Step1: Identify the formula for acceleration

The formula for acceleration $a$ is $a=\frac{v - u}{t}$, where $v$ is final - velocity, $u$ is initial - velocity, and $t$ is time.

Step2: Substitute the given values

Given $u = 20m/s$, $v = 50m/s$, and $t = 30s$. Substitute into the formula: $a=\frac{50 - 20}{30}$.

Step3: Calculate the acceleration

$a=\frac{30}{30}=1m/s^{2}$.

Answer:

$1m/s^{2}$
