Question

The Titanic hit an iceberg estimated to be half her mass. Before hitting the iceberg, the Titanic

was estimated to be going 11.3 m/s. What was the momentum of the Titanic?

Answer 1

The momentum is given as follows:

$$p = mv$$

where $m\approx 46\times 10^6kg$ is the mass of the Titanic, and $v = 11m/s$ is its speed. Thus, obtain:

$$p\approx 46\times 10^6kg\cdot 11m/s = 5.06\times 10^8kg\cdot m/s$$

Answer. $5.06\times 10^8kg\cdot m/s$.
