A boat aims to cross a river that flows uniformly eastward at 3.0 m s⁻¹. The boat can travel at a speed of 5.0 m s⁻¹ relative to the water. The boat points directly north.

Question Parts

( a )
State the velocity vectors of the river and of the boat relative to the water, giving magnitude and direction.
( b )
Determine the resultant velocity of the boat relative to the ground by vector addition. Give the magnitude (to two significant figures) and the direction as the angle east of north.
( c )
If the river is 200 m wide, calculate the time taken for the boat to reach the opposite bank (to one decimal place).
( d )
To land directly opposite the starting point, the boat must aim at an angle west of north. Determine the required heading angle (to the nearest degree) and the resultant speed across the river.
