Q1. The scale of a spring balance reading from 0 to 230 rm{N} has a length of 14.5 rm{cm}. A fish hanging from the bottom of spring oscillates vertically at a frequency of 2.05 rm{Hz}.

Ignoring the mass of the spring, what is the mass m of fish?
State the answer in kilograms.

Q2. A plane leaves the airport in Galisto and flies 170 km 68 degrees east of north and after that changes direction to fly 230 km at 48 degrees south of east, after that it makes an immediate emergency landing in a pasture. When airport sends out a rescue crew, how far will the crew have to fly to reach the aircraft if they fly in a straight line from Galisto?
