1. In 1987, Marisa Canofoglia, of Italy, roller-skated at a record -setting speed of 40.3 km/h. If the her momentum was 660 kg×m/s, what was her mass?
2. 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?
3. 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?
4. 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.
5. 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.
