Question

Calculate the momentum of the titanic (m = 4.2 x 10^7 kg) moving at 14 knots (1 my = 1.852 km/h).

Answer 1

Answer:

$3.02\cdot 10^8 kg m/s$

Explanation:

- The mass of the Titanic is given by:

$m=4.2\cdot 10^7 kg$

- The velocity of the Titanic is given by:

$v=14 kn \cdot (1.852)=25.93 km/h \cdot ( \frac{1000 m/km}{3600 s/h})=7.2 m/s$

- The momentum of the Titanic is given by the product between mass and velocity:

$p=mv=(4.2\cdot 10^7 kg)(7.2 m/s)=3.02\cdot 10^8 kg m/s$
