Multiple Choice
Which object has more momentum: a ball moving at or a ball moving at ?
A
Both have the same momentum
B
The ball moving at
C
It cannot be determined without knowing the direction
D
The ball moving at
Verified step by step guidance1
Recall that momentum \(p\) is defined as the product of an object's mass \(m\) and its velocity \(v\), given by the formula:
\(p = m \times v\)
Calculate the momentum of the 2 kg ball moving at 3 m/s by substituting the values into the formula:
\(p_1 = 2 \text{ kg} \times 3 \text{ m/s}\)
Calculate the momentum of the 1 kg ball moving at 6 m/s similarly:
\(p_2 = 1 \text{ kg} \times 6 \text{ m/s}\)
Compare the two momentum values \(p_1\) and \(p_2\) to determine which is greater.
Conclude which ball has more momentum based on the comparison of \(p_1\) and \(p_2\).
