what is the momentum of a 15 kg tire rolling down a hill at 3 m/s?\no 5 kg·m/s\no 18 kg·m/s\no 45 kg·m/s\no 60 kg·m/s
Answer
Explanation:
Step1: Recall momentum formula
The formula for momentum is $p = mv$, where $p$ is momentum, $m$ is mass and $v$ is velocity.
Step2: Substitute values
Given $m = 15$ kg and $v=3$ m/s. Substitute into the formula: $p=15\times3$.
Step3: Calculate result
$15\times3 = 45$ kg·m/s.
Answer:
C. 45 kg·m/s
