1. Which object has the least momentum? a 0.1 kg object with a velocity of 100m/s a 100 kg object with a velocity of 1m/s a 1 kg object with a velocity of 10m/s a 10 kg object with a velocity of 0.1m/s

To determine which object has the least momentum, we need to calculate the momentum of each object using the formula:<br /><br />Momentum = mass × velocity<br /><br />Let's calculate the momentum for each object:<br /><br />a) 0.1 kg object with a velocity of 100 m/s:<br />Momentum = 0.1 kg × 100 m/s = 10 kg·m/s<br /><br />b) 100 kg object with a velocity of 1 m/s:<br />Momentum = 100 kg × 1 m/s = 100 kg·m/s<br /><br />c) 1 kg object with a velocity of 10 m/s:<br />Momentum = 1 kg × 10 m/s = 10 kg·m/s<br /><br />d) 10 kg object with a velocity of 0.1 m/s:<br />Momentum = 10 kg × 0.1 m/s = 1 kg·m/s<br /><br />Comparing the momentum values, we can see that the 10 kg object with a velocity of 0.1 m/s has the least momentum, which is 1 kg·m/s.<br /><br />Therefore, the correct answer is:<br />d) a 10 kg object with a velocity of 0.1 m/s
