Question: A passenger on a moving train walks at a speed of 1.40 m/s due north relative to the train. The passenger's speed with respect to the ground is 4.5 m/s at an angle of 35.0° west of north.
Part A: What are the magnitude and direction of the velocity of the train relative to the ground?
I need help to solve the above question and please include a sketch with your answer.
