Question

. One of the smallest planes ever flown was the Bumble Bee II, which had a mass of 180 kg. What was the velocity of the plane if its momentum was 2.08×104 kg×m/s?



7. The first human-made satellite, Sputnik I, had a mass of 83.6 kg. How fast does it go if its momentum is 6.63×105 kg×m/s?



8. Among the largest passenger ships in use, the Norway has been in service the longest. The Norway is more than 300 m long, has a mass of 6.9×107 kg, and can reach a cruising speed of 33 km/h. Calculate the ship’s momentum.




BONUS
In 1994, a tower 22.13 m tall was built of LEGO blocks. Suppose a block with a mass of 2.00 g fell from this height. Ignoring air resistance, calculate the block’s momentum at the instant the block hits the ground.

Explanation / Answer

6)180*v=2.08*104 v=12m/s 7)83.6*v=6.63*105 v=8.327kg 8)6.9*107*33*5/18 momentum=6767.75kgm/s 9)v^2=2gh; v=v2*9.8*22.13=20.82m/s; momentum=0.002*20.82=0.04165kgm/s
