Question

question 10 when the net force that acts on a hockey puck is 12 n, the puck accelerates at a rate of 48 m/s². determine the mass of the puck. 2.5 kg 1.0 kg 0.25 kg 5.0 kg 2.0 kg

Explanation:

Step1: Recall Newton's second - law formula

According to Newton's second - law, $F = ma$, where $F$ is the net force, $m$ is the mass, and $a$ is the acceleration. We need to solve for $m$, so we can rewrite the formula as $m=\frac{F}{a}$.

Step2: Substitute the given values

We are given that $F = 12\ N$ and $a=48\ m/s^{2}$. Substituting these values into the formula $m=\frac{F}{a}$, we get $m=\frac{12\ N}{48\ m/s^{2}}$.

Step3: Calculate the mass

$m=\frac{12}{48}\ kg = 0.25\ kg$.

Answer:

C. 0.25 kg
