Explanation / Answer

Given momentum of ship p = 1.25 * 10^9 kg-m/s

we know

momentum = mass * speed

p = m * v

part a)

Given speed v = 46 km/h

v = 46 * 1000 / 3600 m/s

v = 12.77 m/s

from p = m * v

1.25 * 10^9 = m * 12.77

mass of large ship m = 9.788 * 10^7 kg

part b)

momentum of artillery shell is

p1 = 1100 * 275

p1 = 3.025 * 10^5 kg-m/s

comparing with momentum of ship we get

p / p1   = 1.25 * 10^9 / (3.025 * 10^5)

4132.3 times larger
