D) A river of water travels 5 km/hr due east. A driver in a boat observes driving his boat at a velocity of 10 km/hr at an angle 0 with respect to the river flow. A child from a shore observes the boat travelling away from them due north to the opposite shore. a) What is the magnitude of the velocity of the boat the child observes (velocity of the boat relative to the shore)? b) What is the direction (the value of angle 0) that the boat driver observes to be travelling relative to the river flow??

Question
D) A river of water travels 5 km/hr due east. A driver in a boat observes driving his boat
at a velocity of 10 km/hr at an angle with respect to the river flow. A child from a shore
observes the boat travelling away from them due north to the opposite shore.
a) What is the magnitude of the velocity of the boat the child observes (velocity
of the boat relative to the shore)?
b) What is the direction (the value of angle 0) that the boat driver observes to be
travelling relative to the river flow??
