What was the cruise liner’s speed when it collided with the iceberg if it had a mass of 4.23 x 10^8 kg and a momentum of 4.9 x 10^9 kg·m/s?

Understand the Problem

The question is asking us to calculate the speed of a cruise liner given its mass and momentum. We can use the formula: momentum = mass * velocity to solve for the velocity (speed). We will rearrange the formula to: velocity = momentum / mass and then substitute the given values to find the answer.
