A 3 kg object is moving along a straight, horizontal track at a constan speed of 4m/s for 5 seconds. The linear momentum of the object is most nearly A ) 12kgcdot m/s B 20kgcdot m/s C 24kgcdot m/s D 30kgcdot m/s

To calculate the linear momentum of an object, we use the formula:<br /><br />\[ \text{Linear Momentum} = \text{Mass} \times \text{Velocity} \]<br /><br />Given:<br />- Mass (\( m \)) = 3 kg<br />- Velocity (\( v \)) = 4 m/s<br /><br />Now, plug these values into the formula:<br /><br />\[ \text{Linear Momentum} = 3 \, \text{kg} \times 4 \, \text{m/s} = 12 \, \text{kg} \cdot \text{m/s} \]<br /><br />Therefore, the linear momentum of the object is most nearly:<br /><br />A) \( 12 \, \text{kg} \cdot \text{m/s} \)
