Question

question 9 (7 points) use the momentum equation (or the momentum triangle below) to calculate the velocity of an object with a momentum of 100 kg m/s and a mass of 20 kg. v = p ÷ m

Explanation:

Step1: Recall momentum formula

The momentum formula is $p = mv$ (where $p$ is momentum, $m$ is mass and $v$ is velocity), and we can re - arrange it to solve for $v$ as $v=\frac{p}{m}$.

Step2: Substitute given values

We are given $p = 100\ kg\cdot m/s$ and $m = 20\ kg$. Substituting into the formula $v=\frac{p}{m}$, we get $v=\frac{100}{20}$.

Step3: Calculate velocity

$v = 5\ m/s$.

Answer:

$5\ m/s$
