6. Which of the following objects has the greatest momentum? A 1 kg object moving at 200m/sec A 100 kg object moving at 2m/sec A10 kg object moving at 30m/sec A20 kg object moving at 20m/sec

To determine which object has the greatest 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) 1 kg object moving at 200 m/sec<br />Momentum = 1 kg × 200 m/sec = 200 kg·m/sec<br /><br />B) 100 kg object moving at 2 m/sec<br />Momentum = 100 kg × 2 m/sec = 200 kg·m/sec<br /><br />C) 10 kg object moving at 30 m/sec<br />Momentum = 10 kg × 30 m/sec = 300 kg·m/sec<br /><br />D) 20 kg object moving at 20 m/sec<br />Momentum = 20 kg × 20 m/sec = 400 kg·m/sec<br /><br />Comparing the momenta, we can see that the 20 kg object moving at 20 m/sec has the greatest momentum of 400 kg·m/sec.<br /><br />Therefore, the correct answer is D) A 20 kg object moving at 20 m/sec.
