question 12 of 25
a cat of mass 1 kg runs at a speed of 2.5 m/s. what is the momentum of the cat?

a. 5.0 kg·m/s
b. 2.5 kg·m/s
c. 0.4 kg·m/s
d. 1.0 kg·m/s

Explanation:

Step1: Recall momentum formula

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

Step2: Substitute given values

Given $m = 1\ kg$ and $v=2.5\ m/s$. So $p=(1\ kg)\times(2.5\ m/s)$.

Step3: Calculate momentum

$p = 2.5\ kg\cdot m/s$.

Answer:

B. 2.5 kg·m/s
