A knife is dropped from the top of a 10.0 m high mast on a ship moving at 1.75 m/s due south.
(a) Calculate the velocity of the knife relative to the ship when it hits the deck of the ship.
Expert Answer
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.
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...
