A wind is blowing from the west at 50 km/hr. draw the situation and then compute the proper heading and speed the pilot must choose to achieve this objective. and a hobo hops a freight car 15m long and 3.0 m wide, the car is moving east 2.5 m/s. exploring the surroundings, the hobo walks from the southeast corner of the car to the southwest corner of the car in 20.0s; then from the south west corner to the northwest corner in 5.0s. with the aid of a vector diagram, compute the hobo's displacement relative to the ground remember the cart is moving as the hobo is walking AND you can only add vectors of the same kind of measurement please help...i have my final in a couple days and i dont understand this!!!
