Question

a change in momentum cfu (mu)
graph(s) have a change in momentum (increasing or decreasing)

Explanation:

Step1: Recall the formula for momentum

Momentum \( p = mv \), where \( m \) is mass (assumed constant here) and \( v \) is velocity. A change in momentum (\(\Delta p\)) occurs when there is a change in velocity (\(\Delta v\)).

Step2: Analyze each graph

• Graph A: Velocity \(v\) is constant (\(\Delta v = 0\)), so \(\Delta p=0\).
• Graph B: Velocity \(v = 0\) (constant), so \(\Delta p = 0\).
• Graph C: Velocity \(v\) is constant (negative value, but still \(\Delta v=0\)), so \(\Delta p = 0\).
• Graph D: Velocity \(v\) is increasing (\(\Delta v

eq0\)), so \(\Delta p
eq0\) (since \(p = mv\) and \(m\) is constant, an increase in \(v\) means an increase in \(p\)).

Answer:

D
