Step 1

Given:

Height from which knife is dropped, h = 10.0 m

Velocity of the ship, v = 1.75 m/s due to South

We have to find the velocity of the knife with respect to the ship when it hits the deck.

Step 2

Since, the knife is dropped, its initial velocity is 0 m/s downwards. 

The knife would freely fall due to gravity. 

So, a = g = 9.81 m/s...
