a bicycle has a momentum of 36 kg·m/s and a velocity of 4 m/s. what is the mass of the bicycle?\n9 kg\n32 kg\n40 kg\n144 kg
Answer
Explanation:
Step1: Recall momentum formula
The formula for momentum is $p = mv$, where $p$ is momentum, $m$ is mass and $v$ is velocity. We need to solve for $m$.
Step2: Rearrange the formula
Rearranging $p = mv$ for $m$ gives $m=\frac{p}{v}$.
Step3: Substitute values
Given $p = 36\ kg\cdot m/s$ and $v = 4\ m/s$, we substitute into the formula: $m=\frac{36}{4}$.
Step4: Calculate mass
$m = 9\ kg$.
Answer:
A. 9 kg
