CALCULATING MOMLNTUM orresponding questions! ( Force and laws ... \( \begin{array}{l}\text { (B) a scurrying cockroach of the following has the greatest momentum? } \\ \text { (C) a parked semi-truck }\end{array} \)

To determine which object has the greatest momentum, we need to understand the concept of momentum. Momentum (\( p \)) is defined as the product of an object's mass (\( m \)) and its velocity (\( v \)). The formula for momentum is: \[ p = m \cdot v \] ### Known Conditions: 1. **Scurrying Cockroach**: This object has a certain mass and is moving, which means it has a velocity greater than zero. 2. **Parked Semi-Truck**: This object has a large mass but is not moving, which means its velocity is zero. ### Step-by-Step Analysis: 1. **Calculate the Momentum of the Cockroach**: - Let’s assume the mass of the cockroach is \( m_c \) and its velocity is \( v_c \). - The momentum of the cockroach is given by: \[ p_c = m_c \cdot v_c \] 2. **Calculate the Momentum of the Semi-Truck**: - Let’s assume the mass of the semi-truck is \( m_t \) and its velocity is \( v_t = 0 \) (since it is parked). - The momentum of the semi-truck is given by: \[ p_t = m_t \cdot v_t = m_t \cdot 0 = 0 \] ### Conclusion: - The cockroach has a non-zero momentum because it is moving, while the parked semi-truck has zero momentum because it is not moving. - Therefore, the scurrying cockroach has the greatest momentum compared to the parked semi-truck. ### Final Answer: The scurrying cockroach has the greatest momentum.
