Determine the momentum of 1000-kg car moving northward at 20m/s 20000 Joules 20000kgast m/s north 20000Kgast m/s 20000 N

To determine the momentum of the car, we need to use the formula for momentum:<br /><br />\[ \text{Momentum} = \text{mass} \times \text{velocity} \]<br /><br />Given:<br />- Mass of the car (\( m \)) = 1000 kg<br />- Velocity of the car (\( v \)) = 20 m/s (northward)<br /><br />Now, plug these values into the formula:<br /><br />\[ \text{Momentum} = 1000 \, \text{kg} \times 20 \, \text{m/s} \]<br /><br />\[ \text{Momentum} = 20000 \, \text{kg} \cdot \text{m/s} \]<br /><br />Since the car is moving northward, we include the direction in the momentum vector:<br /><br />\[ \text{Momentum} = 20000 \, \text{kg} \cdot \text{m/s} \, \text{north} \]<br /><br />So, the correct answer is:<br /><br />\[ 20000 \, \text{kg} \cdot \text{m/s} \, \text{north} \]
