### Physics Problem: Calculating Impulse Applied to a Hockey Puck**Problem Statement:**A hockey puck with a mass of 0.20 kg is traveling north with a speed of 15 m/s. A Dallas Star forward hits the puck with his hockey stick and, after being hit, the puck is traveling south with a speed of 25 m/s. **Question:**What is the magnitude of the impulse that the stick applied to the puck?**Solution:**When solving this problem, remember that impulse is defined as the change in momentum (Δp), and it can be calculated using the formula:\[ \vec{J} = \Delta \vec{p} = m \cdot \Delta \vec{v} \]where:- \(\vec{J}\) is the impulse,- \(m\) is the mass of the puck,- \(\Delta \vec{v}\) is the change in velocity.First, we need to determine the change in velocity:1. Before being hit, the puck is traveling north with a velocity of \(15 \, m/s \). 2. After being hit, the puck is traveling south with a velocity of \(25 \, m/s \).For the purpose of calculation, let’s consider the north direction as positive and the south direction as negative. Thus:- Initial velocity (\(v_i\)) = \(+15 \, m/s\) - Final velocity (\(v_f\)) = \(-25 \, m/s\)The change in velocity (\(\Delta \vec{v}\)) is:\[ \Delta \vec{v} = v_f - v_i \]\[ \Delta \vec{v} = -25 \, m/s - (+15 \, m/s) \]\[ \Delta \vec{v} = -25 \, m/s - 15 \, m/s \]\[ \Delta \vec{v} = -40 \, m/s \]Now, we use the mass of the puck (0.20 kg) to calculate the impulse:\[ \vec{J} = m \cdot \Delta \vec{v} \]\[ \vec{J} = 0.20 \, kg \cdot -40 \, m/s \]\[ \vec{J} = -8.0 \, kg \cdot m/s \]
