1. A hiker walks 6.0 km due east and then 8.0 km due north, taking 3.0 hours in total.
   Determine the bearing of the hiker's final position from the starting point.2 marks
2. A child pulls a sledge across level snow using a rope. The tension in the rope is 60 N and the rope makes an angle of 35° above the horizontal.
   Calculate the vertical component of the tension in the original situation and state its direction.2 marks
3. A boat crosses a river 120 m wide. Its engine gives it a velocity of 3.0 m s⁻¹ relative to the water, directed at right angles to the banks. The water flows at 1.5 m s⁻¹ parallel to the banks.
   Calculate the magnitude and direction of the boat's resultant velocity relative to the river bank.3 marks
