3. what is the velocity of an elephant with a mass of 5000 kg and a momentum of 12,500 units?

Explanation:

Step1: Recall the momentum formula

The formula for momentum $p = mv$, where $p$ is momentum, $m$ is mass and $v$ is velocity. We need to solve for $v$.

Step2: Rearrange the formula for velocity

From $p = mv$, we can get $v=\frac{p}{m}$.

Step3: Substitute the given values

Given $m = 5000$ kg and $p=12500$ kg·m/s. Then $v=\frac{12500}{5000}$.

Step4: Calculate the velocity

$v = 2.5$ m/s.

Answer:

$2.5$ m/s
