## Step 1<br />Momentum is a vector quantity that is the product of the mass and velocity of an object or particle. It is calculated by the formula:<br />### \( p = m \times v \)<br />where \( p \) is the momentum, \( m \) is the mass, and \( v \) is the velocity.<br /><br />## Step 2<br />We need to calculate the momentum for each of the given options.<br /><br />## Step 3<br />For the 5000 kg car in the parking lot, the velocity is 0 m/s. So, the momentum is:<br />### \( p = 5000 \, kg \times 0 \, m/s = 0 \, kg \cdot m/s \)<br /><br />## Step 4<br />For the 40 kg person jogging at 6 m/s, the momentum is:<br />### \( p = 40 \, kg \times 6 \, m/s = 240 \, kg \cdot m/s \)<br /><br />## Step 5<br />For the 2 kg rabbit sprinting at 15 m/s, the momentum is:<br />### \( p = 2 \, kg \times 15 \, m/s = 30 \, kg \cdot m/s \)<br /><br />## Step 6<br />For the 50 kg table being pushed at 2 m/s, the momentum is:<br />### \( p = 50 \, kg \times 2 \, m/s = 100 \, kg \cdot m/s \)<br /><br />## Step 7<br />Now, we can rank the options in terms of greatest momentum to least.
